Been saying practically the same thing for years. If NFL pay was incentive based I guarantee Dallas wouldn't be about to pass the 30 year mark since their last NFCCG appearance. The players still make the same money regardless because production isn't necessary, and that's a load of horse manure if you ask most people. The NFL would be far more competitive if the players actually had to earn the 'bags' they keep demanding.
We all know this is a system that will never be implemented, though. There would be a full blown riot by many of the players if they found out they had to try rather than just going through the motions.
