Tony Gonzalez spoke against the NFL's structure of paying players based on position.

"I can think of a few terms to describe what's going on in the NFL, like 'backward,' 'lack of common sense' or 'behind the times,'" Gonzalez wrote on CBSSports.com, "but the one that makes the most sense is 'discrimination.' Salaries should be set based on production and contributions, not positions."

Gonzalez believes the NFL needs to create a new hybrid designation for tight ends starring in the "joker" role first popularized by Kellen Winslow Sr.

Unfortunately, the NFLPA's hands are tied on this issue until the current CBA expires early next decade.
