They list Blanton as 262 lbs. That's a big TE. He sure doesn't look like he's that big. But... he might be like Donald. Muscle mass weighs more than fat. AD is so ripped that he weighs more than he looks like he ought to when he stands next to other Dlinemen.
Maybe Blanton is ripped, too, and that 262 is real and all muscle.
In addition to blocking, that young man is a hands catcher and good athlete. Perhaps another Snead find who only needed playing time to show what he's got. Now let's see if ever gets a chance to run a typical TE seam route.
