I Didn't see anything amazing on his highlight film. One film pointed out his blocking, yet everyone of his "highlights" ended with his guy making the tackle. Granted that his block added about 5 yards more to the run, but he looks lazy in his blocking, and gives up on them fairly quick, and he's not driving the block, he's just staying in front up the guy, making sure he doesn't have a clear tackle. I want to see them driving the block, and making space... In the NFL, you have to stay on your block until the whistle.
On of the highlights said "QB threw high and behind him", to me it was a bad throw, but it hit him in the hands... you catch those, not every ball is a perfectly placed throw.
I reserve judgment, I hope he becomes what Givens was... but based on what I saw of his highlight film, he looked pretty average for a college WR, and in the NFL, I just don't know.
Of course, there is always room to surprise me.
