Jereme Richmond sticking around another year(and getting his crap together) probably would have helped oscar at Illinois.
D.J. Richardson being a decent player but not living up to his Top 50 ranking probably didn't help.
Finishing 2nd on Jon Scheyer didn't help.
Probably biggest "woe" was having Sampson and Indiana swipe Eric Gordon away. 1 and done but still a big time player who might have been able to alter the momentum of their program ala Beasley. Don't think Coach Chester likes him too much.
Well, not only that stuff, but losing Jamar Smith (now a fringe NBA player), losing Quentin Watkins around the same time, having Demitri McCamey being just good enough (and a 3.5 year starter) to dissuade other PG prospects from coming. Our backcourt was a mess for a while.
His last team was the most talented he had recruited. The wheels fell off right after we knocked off Ohio State.
As to my comments re: Kansas and Texas Tech: oscar had a great record against MSU, the class of the big 10 during his tenure. His teams struggled more than they should have against Penn State.
