Thru 4 games he has 18 reception for 203 yards. He has almost no yard after the catch... Proves he lost a step. He had similar stats when Chris Weinke started in 2007 and Jimmy Clausen in 2010.
Take away the Arizona game and his stats don't look that bad.
And as for the Zona game.
2005 week 4 GB 2 rec for 16 yds.
That was in the middle of his triple crown.
