As evidenced by the game last night, I don't think any one big guy would be detered from joining the Illini because they fear they wouldn't get minutes. There are plenty of good minutes available for 2 or three quality low post players. You can only watch teams like IU run a tip drill at their basket so many times before you realize we need a LOT of help on the boards.
The only time I've seen anything come into fruition since I joined IL in 2012 was from a poster ("Josey Wales," I believe) who had the one-time scoop from the newspaper D.J. Williams made his commitment in.
99% of the posts in these recruiting forums are speculation and an anxiety feedback loop about the status of the program.
