Those schools have very, very deep pockets and programs with high expectations. The school's leadership know it is smarter to send coaches packing a year early, if necessary, rather than a year late. Rutgers can not do that. Unlike Rutgers, which has probably surrendered 10 years of dreadful recruiting classes over the last 30 years by waiting too long before showing a coach the door, Indiana and Ohio State did the pruning necessary. The recruiting classes of Indiana and Ohio State will surprise many.
Lots of hand wringing over Tom Crean at IU, going back to 2014. Boosters wanted him gone then, AD stuck by him. Even gave him a public vote of confidence in the spring of 2015. Deep pockets or not, it would have been very expensive to fire Crean in 2014 or 2015, their AD may have lost a little bit of sleep while IU wasn't getting back to where they were in the distant past and Northwestern, Purdue, Iowa and newcomer Maryland were making B1G moves.
I don't know that their recruiting classes will surprise many -- unless their expectations are low.
The expectation is that Miller is a very good recruiter and now he'll have IU's resources.
Holtmann brought his staff with him from Butler and they're working hard to get involved with Tim Finke, Luther Muhammad, Dwayne Cohill and Jeremiah Francis to name a few top prospects. They have five spots to fill. They already flipped Kyle Young for 2017.
