In a two vs two match - stop thinking about doing it all by yourself, and start thinking how you can maximize the chances of the alliance. A poor robot partner can do 10 or less points in qualifiers.
A fair partner can score between 10 and 20 pts.
Good - 20 to 29. Excellent 30 or above. How it does it is not as important as how consistently it does it.

There are two ways to get in the elimination round. The first is to qualify - here a well rounded design is probably going to prevail. - The second way is to have an oustanding capability (probably
defensive) that makes you a good alliance pick.

Look at the 2000 game (In which team 255 won the national championship.) The 255 robot was one of the simplest designs in the competition - 4 motors, no pnematics, FP drive motors, but it reliably could score 22 points in about 45 seconds which was enough to win 10 out of 12 Qualifying matches.

During the elimination rounds the 255 robot played
4 out of the 12 matches - relying on two allies who
were primarily defensive.

There is alsways a danger in having a robot that is
defensive - even if it is great at defense, it is going to have low QP. Defensive play during QP does not contribute to any potential ally QP. Only a spectacular defensive/offensive capabilty - i.e.
one robot that can grab and control all 3 goals, and move at least one into scoring position would be a good candidate, as could a bully bot who could always capture and tow an opponent back to it's home zone

"Ask not what your robot can do to your opponents,
rather ask what your robot can do for your alliance"
