You missed my point, or simply choose to disagree with it, which is your perogative.
If you think a hardcap (in concert with the inevitable liberalizing of player UFA rights) will not result in increased player movement, see the NFL.
Even at a lower pay scale, players will actively seek the "best" deal....and opportunities will be there, even moreso than today.
More free agents = more job openings = more movement. The middle-to-lower level player will become more devalued under a cap, and hence more easily (and more frequently) replaced, salary-slot-wise.
Given your remark on another thread, however, it's not worth the time trying to explain this point further. If one wishes to ignore the realities of the detrimental effects a hardcap can have on roster continuity leaguewise, based on past and present history right before them (read: NFL), indeed, ignorance is bliss.
