The only thing he was lacking for me to put him in that category was the big game heroics that Watson had ie; last second TD the 2nd time they faced Bama for a Nat'y. What he did to Bama in those 2 Naty's was nothing short of amazing, especially because at the time, they were calling that the best Bama D, ever!
Fields really didnt have the defining game until Clemson. As many TD's as incompletions, a 6 bomb on the juggernaut that is Clemson while completing and utterly outshining the golden boy both on the field and on the sidelines. It was man vs. boy in that game.
If it werent the Nat'y, I dont think Fields plays. They knew he was injured and I want to say he only saw a 4 man rush like a handful of times, they were bringing the heat on him and he clearly wasnt 100%.
