Mason is not in Devine's league in terms of physical potential. Devine has all the physical tools to be an elite caliber OL. In terms of elite physical tools for his position, he's probably in Calvin Johnson's league...that's saying a lot. Coaches have a saying for guys like that "He can be as good as he wants to be." He said the same thing about Waller...and we're kinda seeing it play out in the draft process for Darren. Had Darren taken his physical gifts as seriously and worked on his craft like Calvin, Demaryius, Stephen Hill, and Smelter did during their careers, we might be talking about how GT will have a first round draft pick this year. That Waller is getting mentioned on potential alone after a very modest career here tells you how much more productivity he could have had for us.
I think Devine is absolutely in that category. If he works at his craft, and makes use of the resources GT has to get his body in peak physical condition for his position, his ceiling is as high as any athlete we've had here.
