IMO, even more important than seeding, is matchups and style of play. With our Illini all over the place, it's been hard to figure out what type of teams we play well against. But the PSU, Iowa, and IU games have given us our answer. We can't win shoutouts. We do much better in the ugly, dirty, slower paced games. Think Rutgers, MSU, and Wisconsin.
So some of the top seeds we could really matchup well with are Tennessee, St Mary's, UCLA, Iowa St, etc. Teams that are defensive minded and/or play really slow.
Teams to stay away from....Bama, Arizona, Gonzaga, Marquette, UConn, etc. These teams rely on their scoring, getting into the 80's and above, and many of them also play fast.
