First, the guy broke his leg, didn't lose his leg. A broken leg is usually easier to come back from than a torn ACL. Washington barring some freak complication will definitely play again.
Second, this type of thing will most likely not be addressed in the next CBA discussions. The NFLPA does provide their own compensation for players who are forced into retirement due to injuries already. There will never be a league run disability plan. Also, being in his contract year, Washington could have bought insurance from Lloyds of London against injuries like this (he may very well have). Many athletes on the verge of free agency insure themselves in case of injury based on their perceived value.
Third, the Jets did offer Washington a new contract for $4 million a year which he refused before the season. If I was Washington, I would have refused it too seeing how Michael Turner worked out as LT's back up and then cashing in as a free agent getting more than Washington was offered. But this isn't a case of a team refusing to renegotiate with a player who is under a rookie deal. The Jets wanted to extend him, but their idea of his value and his idea were not on the same page.
