The giant point coming across in the last few posts, as you contend, is that the least important thing in football is the talent, because everyone has it at the highest levels of their sport. Some just know how to use it better than others. It's a given that the top 2-3 teams in any college or professional conference or division are going to have somewhat similar talent. It only matters when there is a huge discrepancy in it between teams. When teams are relatively similar with regard to such, all the other stuff matters way more.I agree, but I wanted to stay with just the QB. Also, very few adjustments are revolutionary. Guaranteed the offensive scheme MY uses has counters to those adjustments. At halftime and an experienced QB, PSU would have been able to counter. With the backup QB that had no experience, not easy to do. Then you factor in player confidence without Clifford which is hard to quantify. PSU had won I believe 10 straight coming in to that game. Confidence was probably sky high, that injury also affects psyche.
When you reach a professional level or even top college level the talent is pretty similar. Most of the stuff comes down to planning, psyche, confidence, experience, continuity, knowhow, smarts, adjustments, etc.
So here's the trick to all of this, when you're good at all those intangible things I mentioned above, you can take a player that maybe has C+ talent and he may be able to play at A- performance level. It's why guys often produce completely different, better or worse, when they get traded or leave a team in free agency.
