Yea, I have a hard time seeing many WRs push Joyner around. Don't judge a book by its cover, my friend.
As far as jump balls are concerned, throw jump balls in Joyner's general direction at your own risk:
By the way, the guy he ko'd in that video was a 225 pound HB.
Skip to 1:57, you see his range as he comes flying in from the hash mark to blow up Michael Floyd on the sideline and it took Floyd awhile to get up.
Blitzes the QB forcing him to dump it off and then makes the TD saving tackle 60+ yards down the field.
LaMarcus Joyner is an amazing football player. That's what I want on my team. You can keep the 6'2" athletes...I want great football players. Don't care what package they're in.
