First round matchup as an 8 would be Illinois, 7 would be Indiana, 6 would be Rutgers/OSU. I think Indiana might be the worst draw there.
As for the second round, 8 is Purdue, 7 is Wisconsin, 6 is Maryland. Wisconsin is a messy situation, bad match-up and they need a bounce back win and don't have a great RPI. Purdue is a fine spot if you don't need a win, since it wouldn't hurt at all to drop that game and would help a ton to win it.
IU in the first round would feel like a major trap... they have a lot of talent and can score the ball.
