Manning was smart enough to get WF to pony up not one, but two multi-million contracts with some solid buy-out protection.
The lazy accusation is just so baseless and plain wrong. Manning made more than $60 million in his NBA career. He literally could sit on his arse for the rest of his life and still take care of his family for generations. Instead he took an unpaid graduate assistant's position at KS, and legitimately worked his way up the coaching ladder in Lawrence, a top 5 program, to become assistant head coach for a program that went to multiple final 4s and won a Natty while he was on the staff. Manning then took the Tulsa job, and took them to a conference championship and an NCAA bid in year 2. While he has generally failed at WF, there was no sign that the poor results were attributable to a lack of effort.
Coaching in the ACC is hard. Lots of smart and hard-working coaches have failed at this level. So misguided and juvenile to assign personal flaws to those that try and fail.
