Well, first, McCord has a pretty good season at Syracuse with far less talent (and played against far less talent). I'd also add that McSorely was very good. But PSU has never gotten the five star talent that tOSU and UM get. PSU really hasn't had a elite QB since the 90's so it is a challenge to recruit.You ignore the coaching input. I can't remember one qb who really thrived under James Franklin. One pretty good qb who Franklin was unable to utilize was Will Levis. Ryan Day took Howard over McCord and turned Howard into a very good qb.
Specific to Levis, his problem was that Sean Clifford started over Levis. He was a year older and had a year of experience under his belt before Levis challenged him. CJF chose Clifford and Levis transferred to KY. Sadly, we had no second-team quarterback which probably cost us two games: Iowa (who was highly ranked) and the 9 overtime game vs Illinois. That was also the crazy year we were trapped in Sparty's crappy locker room for many hours with no food or supplies while Sparty feasted. We'd have probably ended with a two loss season (tOSU and UM)
