Bills - lose the player and the red shoulder patch. 
  
Pats - going back to old school.  Can't decide if I like it or not. 
  
Ravens - downgrade from current logo 
  
Bengals - Tiger prawn?? 
  
Steelers - what's the significance of the three bars?  The three rivers?  It doesn't work for me. 
  
Texans - would be good if the Chicago Bulls hadn't done it first. 
  
Jags - not much different from current logo 
  
Titans - lose the flowing hair and you might have something, but their current logo is too sick to change. 
  
Broncos - if you were marketing My Little Pony, maybe.  That's an abomination. 
  
Chiefs - too complex, and the arrow suggests pointing to the past instead of the future. 
  
Chargers - seriously, what is with these animals curving like shrimp? 
  
Cowboys - No, just no.  That's an L. 
  
Giants - is it a logo or a subway system map? 
  
Eagles - another too similar.  If you are going to redesign it, then REDESIGN it. 
  
Bears - is it a bear?  Is it a wolf?  A dog?  What is it?? 
  
Lions - looks like something from the Lion King or other kids' cartoon.  Awful. 
  
Green Bay Packers - interesting.  Would never have the fans' buy-in.  Now excuse me, I have to go watch a Legendary Pictures movie 
  
Vikings - what the heck is that??  Looks like the king from the LA Kings jersey.  Terrible. 
  
49ers - the football at the bottom looks like a zero.  Bad idea. 
  
Seahawks - not bad considering the current logo is one of the most awkward in the league.  Not much room for a new direction here.
