True but with Lawrence and Fields, because the talent on their offense is so much better against the defense they're playing, it's hard to gauge how good they'll really be when they go up against a defense that is equally talented. Especially with Fields, you look at all those slow and prodding Big Ten defenses and how much faster his skill players are. And he rarely gets touched his OL is so good against the defenses they played this year.
This is a general observation obviously and not an absolute. Both could become great NFL players. Watson for example is one of the best young QBs.
