If more NFL players had this attitude, their teams would fair better in the win/loss column. The "all about me" mind set does not make your team better. Stafford and Kupp were the best tandem in the NFL last year, but neither have asked to be paid the top dollar.
I read and hear who the sports talking heads say is the best receiver in the NFL, and Kupp's name is never mentioned. But the stats say otherwise. When the pressure is on and the game is on the line, there is no one better to receive the ball than Kupp.
