Fast is a relative term. Will he ever be as fast as a 6' 3" 240 lb TE? Nope. Is he fast for a 6'8" 280 lber? Yes! And, not being fast does not equal not athletic. The dude is very athletic for 280. Witt isn't fast, but he gets open because of his route running. Rico will get open simply because of his size. If a 6' 200 lb SS is glued to his left side he is still open on his right side! Seriously, how do you guard that on the goal line? And because he is athletic he can also become a very good route runner. The fact that he has been working OT during practice is a major plus, he will be like having a sixth OL in the game, but one that you have to cover. I do think, once Witt retires, they will want to pair him with a smaller TE/H-back.
