Mason is 6′1″, 300 pounds for those who didn’t know, but Belichick still called him the best run blocker in this draft class. It will certainly be a challenge for him as usually 6′2″ is about as small as interior OL go.
But the advantage that Belichick touched on was that Mason knew how to use leverage and height doesn’t have much to do with anything when you’re on the move and trying to get in front of someone.
It was mentioned that Mason was seen working as part of the wedge on kickoff returns and that’s a spot where he could really be deadly. He certainly seems to have the kind of playing temperament they look for, but whether or not he can hold up in pass protection against guys who are five-plus inches taller than him will be something to monitor.
I am not expecting that he comes in and plays on offense as a rookie.
