I think it's important to note that Niswnager had an important role in the negotiations because he was doing it all while not knowing if he'll even be back with the Chiefs. Because of the rules that moves free agency back to a four-year threshold, Niswanger is scheduled to be a free agent now.
Will he back in KC next year? He tells Bob Fescoe on 610 Sports he's not sure yet.
I don't set any expectations for this period. We'll just have to see how it plays out. If other teams are interested, and the Chiefs are interested, I'll have some decisions to make after that. That's kinda the way I'll leave it.
In a short offseason, I'd bring Niswanger back -- at least to camp. The Chiefs can determine from there what they do with him but my official guess is that he's in Chiefs camp.
It sounds like the negotiations between the owners and players ended on a good note so I wouldn't expect any backlash against Niswanger because he's a player rep.
