The NFLPA not reforming as a union is not an option, for the NFL to continue it is a necessity. I am not going to sit here and lie to you, saying that I am smart enough to know how the negotiations would have proceeded without the NFLPA decertifying but the fact is they stated they decertified in order to get a new deal done. That deal is now (99%) done and its now their responsibility to close Pandora's Box. 

Without a union in place it is just a matter of time until one player (and his over zealous agent) wants to challenge the draft, the rookie salary cap, the economic system of the league in its entirety and all of this work/progress will be for not. The league will be found in violation of anti-trust laws, the draft and salary restrictions will end and, most importantly, parity in the league as we know it will end. 

A team like Philadelphia, in a major market with an owner that is willing to spend $$$, will not be as affected as others but teams like the Cleveland Browns, the Jacksonville Jaguars, the Buffalo Bills can forget about EVER again picking up a true 5 star prospect. They will quickly become the Kansas City Royals, the Pittsburgh Pirates. The gap between the haves and have nots will spread to distances never before imagined and the competiveness of the league will become a thing of the past. The thing that makes this sport so great, that anything can happen on any given Sunday, will be forgotten and the NFL will join the other 3 major sport leagues in mediocrity where no one tunes in (or cares) until the playoffs start.
