Illinois, MSU & iu all have potential to be F4 teams. Probably won't, but each have talented athletic players and combo of experience & talented youth to get it done.
As far as the others....don't know about Iowa or Mich as haven't watch them yet. Whisky always seems to be top 5 in B10.
I like Purdue but I see them as a mid pack (4th-7th) B10 team & maybe a top 30-40 team. Obviously if they are 4th in the B10, they are a top 20 team. But more likely they aren't & not a top 20. CMP's starters are far too weak @ the 3-4. They both will be towards the bottom of the B10 as far as production at their position. And more concerning, we will see if our frosh guards don't hit a wall in Jan/March as they are being asked alot of? Finally, ZE will be productive, but not sure how far that takes us? Still with our young core of guys I am excited to watch their development all year.....hopefully they squeak in & get a ncaat run.
