hixon cant stay healthy. Hixon is faster can run better routes and catches better. He is more complete. manningham is more elusive with the ball in his hands and he always catches the ball with his body. I like manningham also but i know hixon is better. he is in a little slump right now along with the offense but you got off to a very good start this year and has been making plays for us.
Just look at the productivity of the two players. And they've been on the same team with the same guy throwing them the ball for almost all of it.
