IRI is always tough to predict because of the rule changes and the extra five pounds per robot, so I think that the best predictions are simply the alliances that you have always wanted to see face off against each other. Then go from there. Here's what I want IRI to look like:
Alliance 1: 2826 - 118 - 27 W
Alliance 2: 148 - 1114 - 195 SF
Alliance 3: 2056 - 1023 - 1730 SF
Alliance 4:624 - 469 - 125 QF
Alliance 5: 3824 - 33 - 2614 F
Alliance 6: 330 - 548 - 1218 QF
Alliance 7: 1325 -2468 - 16 QF
Alliance 8: 3641 - 379 - 4143 QF
This list excludes fourth picks, as very few of those robots would actually get to play.
Alliance 1: 2826 as first seed could pick 118, a two can grabber with good landfill speed. Their second pick could be 27, so that 118 could push out tote stacks while 27 can cap with cans and noodles quickly.
Alliance 2: 148 is second seed and decides to choose 1114 ( assuming: they have a fancy new can grabber that doesn't break when grabbing cans). 195 is a good feeder bot and an excellent second pick.
Alliance 3: 2056 as fourth seed has been bumped up a spot and decides to choose the sixth seed 1023. 1730 matches up nicely as a second feeder bot.
Alliance 4: I just want to see this alliance. I don't even know why; I think it would be cool to see.
Alliance 5: 3824 is a good three stack robot. They pick 33 so they have a good landfill bot and a three tote autonomous. They pick 2614 because they know them from a previous competition [

] and they know that they can get a solid two six stacks from a feeder. This equates to 7-8 stacks per match.
Alliance 6: Another cool alliance I want to see play.
Alliance 7: Two feeders and a landfill. Solid alliance.
Alliance 8: The Flying Cat Wars alliance. Who doesn't want that?
