Don't care about comparisons on overall units but none of the receivers have the upside Demaryius Thomas has. After he returned to full health he was the number 2 receiver in the NFL for the last 7 games. Handicapped by a run first offense and Tebow. Just wait to see how good he is with a real QB.
Decker had 8 TDs. I like Floyd but I'd say Decker is younger and has a lot of upside with Manning. Floyd does have some hops though. He is underrated by most fans.
Bolt fans haven't seen Decker or Thomas with a real QB. The Bolt receivers have had the edge in that department. Perhaps this year will tell us more.
