It shouldn't. If Ferguson says this helped him, why would any reasonable person find fault in it?
But people like Pappy will always turn even what's a positive story into a negative, no matter how irrational it is to do so.
If you look back, Pappy's history is to disappear from this board when things go well, then reappear when they don't. In the past he has argued that Dak isn't even good enough to be in the NFL. Reasonable people can disagree on whether Dak is the right guy to have behind center to get to the championship. but no reasonable person can claim he isn't even worthy of being in the NFL.
