We also do not know for certain that the NFL has refused any compromise. They are not issuing their stances publicly, so the only way we will know if that is the case is if the "last, best offer" is identical to the first offer... because the NFLPA is certainly not going to come out and say, "Oh yeah, the owners had concessions but we didn't like 'em"...
Not at all true. Each point in the CBA is a separate issue, meaning if the NFLPA and the owners agree on the rookie wage scale and the retirement benefits, but the owners try to force the 18 game season and the profit share down the players thoats making no concessions and telling them to take it or leave it, then the NFLPA can still file charges against the NFL for a lack of good faith bargaining. The NLRB considers the following when deciding if an unfair labor charge for surface bargaining has taken place (funny...I already posted this prior to the NLRB suit filed by the NFL today)Prior bargaining history of the parties, parties' willingness to make concessions, character of exchanged proposals and demands, ANY dilatory tactics used during negotiations, conditions imposed by either party as necessary to reaching an agreement, unilateral changes made during the bargaining process in conditions subject to bargaining, communications by employer to individual employees, ANY unfair practices commiteed druing bargaining.
The owners have violated several of those considerations. The NLRB may be looking into the players union because of the owners suit, but this board is unbiased and implemented by the US Congress. They will not buy into the owners BS and they will uncover any boulwarism and surface bargaining tactics.
This is really going to get interesting...not like the NFL draft interesting, but interesting all the same.
