Yep, that's my exact concern. Calvin Johnson is essentially the same size. He's listed at 236, but it wouldn't surprise me a bit if he's 240+. But again, he's a freak.
When you look at KB's measurements and times, they scream elite NFL TE. They don't scream WR.
The same can be said for olsen. Hes more a wr than a te. But the fact of the matter is the kid is a football player a weapon who cant be defined by a simple position. Yoy can play him te or wr and he wins. That's a valuable asset this day and age.
