McNeill has been very good, but I don't see him winning ROY. There have been to many strong players at skill positions to give it to an OLineman. I'm not saying that he isn't deserving, but it is rare for the voters to go in that direction.
He won't, anymore than an OL will win the Heisman but he's being discussed in that realm by people.
You know what, OL need stats. I think that's why they get no love. Someone needs to push to statify the OL position.
