When we're in drafting or near drafting position, we always make a list of 24 (+/-) teams, and put them in order of who we'd like to be with based on their performance and how well they'd compliment our robot. For example - at Midwest Regional, we knew we needed a robot that could move balls for us, so we went with 469. Of course, the list can change based on performance on Saturday... and it does, the friday night list just really gives us an idea on who we should be watching closely.
