How do you scout Defense?

Two key examples. In the MSC finals, 217 played defense while 67 and the 3rd bot (sorry I can't remember their team number) played offense (to some degree). In Palmetto finals, we choose team 1398 to primarily aid in defense and home zone clean up. Both robots had VERY strong drive trains and BOTH robots played exceptional matches.

Wait? There was another robot besides Hot and the Chickens?

I realize you might not be intending something as extremly rude as you have stated, but this kind of thing bugs me. If you have ever been there (as the 3rd pick or as the alliance captain), then you would know that the 3rd pick is the make or break of an entire alliance. This is a TEAM game. The most complete TEAM will win more matches.

See? Kids never can spot sarcasm til puberty kicks in. Yet another reason to advocate the installation of a Sarcasm Button here.
The team he is talking about that no one else is, is his own so he's being ironic as well.
Unless you are one of the elite teams the fanbase is so in love with around these pages you're most likely going to be forgotten outside of your own area. I wouldn't make too big a deal of it.

This year the best kind of defense is to have a robot that can kick all the balls out of the far zone. That is much better than a robot that only gets in the way of the opposition for two reasons.

1. Your opponent can't push balls in that just got kicked down field.
2. You can't score something that is down in the far zone.

So 1718s offensive rankings are pretty useful. You just have to put kicking balls fast out of the zone as more of a priority then aiming and scoring.

(also great job 1718 you guys were fantastic partners, we almost had 67, 217, 2612 in the semis!)

I'll remember 2612 Jack, at least until I get to Atlanta and a new set of finals! You were in my corner most of the time scoring goals.

But as to the question, if you watch 217 play defense, and not just against 469, then you have the characteristics, as has been stated. They are extremely tough, low CG, quick back and forth, and top it off by being able to grab a ball and fire it out of the zone. And of course good driving and coaching (which without, the bot would be far less effective).

Of course a team and bot like this will likely never be second pick but I think it proved to be a wise choice to have a strong offensive team playing defense in the several occasions they did.

As helpful as qualitative data is, you will not make good defensive picks using anything but your smartest minds watching the field and figuring out what people are doing.

If you're looking for "who pushes the best" or "how long a pin they have" or whatnot, you're not looking for people who play smart defense. Sometimes the smartest defensive move is not to move, something many drivers don't seem to fathom. Blocking a goal or herding a ball is often better than trying to push or pin. (See QF1 and QF2 at WPI for a direct comparison of these methods )

This implies that pushing defense around is not smart defense. After watching 171 in Wisconsin and 2041 in Minnesota, pushing defense is certianly effective. Obviously, this is not the only way to play defense, but it is the way that requires certian traits of the robots. Anyone can sit infront of the goal or herd a ball, but not everyone can push and pin. The alliance partners can tell a robot with 8 traction wheels to sit in front of the goal and not move, but cannot tell a robot with a mechanum drive to push other robots around.

I think this just underscores the point that you cannot pick teams just based off one thing. You don't just pick a team based on the fact they have scored the most goals nor do you pick a team just because they can push anyone. There are many many factors that need to be weighed.

I would like to second this; in particular, I cite a qualification match my team was in at DC. We are a defensively designmed machine, and as such we typically played in the third zone. With DC as a week one regional, we experienced the infamous losses of connection and thus frequently lost all control of our machine at random during a match. During the particular match I'm thinking of, we lost comm about 20 seconds into the match, but had managed to wedge the balls against the wall and park right in front of the goal, allowing us to sit there providing airtight defence. I specifically remember this match as being hilarious afterwards, as our teammate complimented our driving, despite the fact that we were unable to move for the majority of the match.

A sharp eye, a strong idea of what you're looking for, and a little bit of luck. Most importantly, reasonable expectations of what they should be doing within your strategy.

No offense to any teams, but most "defensive" teams are a dime a dozen. There will be a couple of standouts in terms of defense, but they'll be easy to pick out. The next group of teams will be almost identical in terms of what they're going to be able to give you on the field, and I highly suggest that you pick based on reliability and robustness (which is pretty hard to scout effectively).

The damning factor in picking many teams is identifying how they play against the higher caliber of competition in the elimination rounds. I've seen many picks, including some of my own, end up being the downfall of an alliance because they can't hang in against better opponents. They may have chewed up the weaker foes in the qualification rounds, but they simply can't keep up with the faster, more agile, more reliable, and/or better driven teams in the eliminations. If you notice that a team on your pick list struggled (in whatever given role) against an elite team in a match or two, it should send up a warning flag.

[Sumathi]

It depends on the type of robot you use, and your game strategy. For example we play offense so we work around that. Anyways things to scout for would be speed, sturdienss, manuverability, how they move balls across the field, the drivers themselves, what the robot was built for, also add on qualities that your drives feel are necessary in a defender.

[NullEntity]

Funny, I came here to post the exact same thread.

What we will be implementing for Atlanta is a scale of 1 to 3 on how defensive they are. Last year, we tried counting pins and everything (they were more applicable then), but of course it was extremely tedious.

[quote=BJC;947922]This year the best kind of defense is to have a robot that can kick all the balls out of the far zone.

I agree with BJC. The faster you can get the balls out the better for your defense and your offense. I have seen many robots block the opponent effectively only to have another come into the zone and score the balls that have accumulated into the unblocked goal.

Just to keep me sane, let me recap. Some of you are saying that kicking balls out is the best defense. Others are saying there is nothing you can keep track of with numbers about defense, and yet others are saying to compare avg balls scored to what was actually scored in the match for the team that is being defended. Did I miss anything?

Oh and Lil Lavery, if you think defensive teams are a dime a dozen, then you obviously havn't been paying close enough attention. Picking the right defensive bot has made and broken many finals alliances. These teams were diamonds in the rough at the districts my team has been at, and we are kicking ourselves for not picking them.

I totally agree with you as our teams scouting captain and strategist the 3rd pick can make or break the alliance. And you have to pick the right defensive bot that works best for you because my idea for defense is a bot that can keep up with the lead offensive bot and to be able to push balls in occasionally thats my idea

[Zach O]

Our team has found no reliable way to scout defense. I know several team's that scout defense based on their scouters ranking them, but that leaves grey area in your data. You can't be sure that 2 people would rank the same robot the same "defensive ranking score". I think the best way to scout defense is just to have someone out there watching and taking notes. Do they consistently play defense, or just when they get stuck with it? And how well do they play defense when they do? The only way not to get mixed results from this is if a singular person, or a small group of 2-3, watches the matches and takes notes.
