Taysom is a thick dude. When they showed clips of his BYU pro day it reminded me of Tebow. Actually, I think Tebow could have done much of what Taysom is doing had he not be insistent on being a QB only.
Kamara has choppy feet and a skinny running style with great burst. He also gets the Pierre Thomas dead leg syndrome when defenders hit him. It's like he let's that part go limp and absorb the blow while keeping his balance. Very impressive. He also is the fastest runner I've ever seen that looks like he is just trotting along.
