Because they're both white? Westy doesn't thave the speed, quickness or the moves that Edelman has, that's a pretty terrible comparison. Amendola might be a decent comp, though.
Guess that's your opinion as it had nothing to do with race.
Westerkamp
Height: 6'0"
Weight: 200
40 time: 4.5 seconds according to the link above.
Vertical: 40"
Edelman
Height: 5'10"
Weight: 200
40 times: 4.52 at the combine
Vertical: 36 1/2"
At first glance, you're wrong based on what you're saying. Clearly Westy has the same speed, the same size, the same UPS if not better, he has fantastic hands. Unfortunately we won't get to compare NFL combine numbers so it'll be interesting to see how things go with those numbers on down the line. Now if you want to say that Westy can't seem to get his hips engaged at times and seems stiff in that area then I might only agree with that assessment. And remember, we're comparing a soon to be rookie to a seasoned NFL veteran so of course he's not going to have some of the same development yet that Julian has.
Watch it and try to remember:
I think Westy has the edge at the same point in their careers since he is already a WR and Edelman converted over from QB
