Even that clip shows his lazyness. As tall as he is, he just waits for the ball to come to him instead of goes up and gets it. He was good at catching those, but never improved due to his attitude.
He could have been a really good to great WR, but really went off the rails after his mother's death.
Sad to see, but after his comments on Cam, he made his own bed. No one wants to put up with that crap without elite production.
