What he said has some truth in it. Doug Marrone took over a program that was one of the worst 5 BCS jobs when he arrived and changed the culture around the program. Marrone took over a 2 star program and used pieces left by the previous coaching staff and turned the program into a 3 star program. I don't think Marrone left 9/10 win talent on this roster, but he left enough talent for this coaching staff to get to 6 wins and continue the momentum. While I don't think Marrone left the cupboard full he didn't leave it bare either the groceries left in the refrigerator weren't enough for a 5 course meal, but he left enough groceries to make a decent meal.
I don't think Marrone in the near future i.e. next 2 years was close to having 9/10 win seasons unless the kid down at TCU Zack Allen turns out to be a stud, but he would have continued the 7/8 win seasons and gotten us better. I was never disappointed Marrone left SU for the NFL, I was more disappointed in how he left. It felt like he left in the middle of night and took a lot of the stuff he built with him when he didn't need to do that.
