If he is legitimately 6'5" then he could most likely get to 260-270 easily and be an every down DE for us. What is the problem with that?
I agree that he physically could. You have to ask how long would that take with his frame and would he be able to keep the athleticism at the level needed if he put on that much weight. I guess I am just not as thrilled with him as others, but if the coaches choose to offer him I won't be unhappy. We are recruiting some more 3rd down players, so if that is all he ever is, and he can do that successfully, I'll be content.
Edit: If he is already filling out his frame then maybe I am totally off. I'd rather be wrong here.
