See that's the crux of the whole problem.
Only one side has been using leverage to try to create high pressure situations through this whole process.
The owners didn't have to lock the players out. Negotiations could have continued without a lockout, as could the entire off-season. They could have also attempted to offer to negotiate in good faith while working under the structure of the old deal until which team that a new deal could have replaced it.
The owners didn't have to sit on a players offer for 43 days and not negotiate at all during that time frame.
The owners have cried "last and final" on now four different occasions, and yet here we still are.
I have yet to see the players threaten to strike, or refuse to negotiate for long periods of time. The longest response time I can recall to an owners proposal was two days.
The closest thing I have seen to a threat from the players I have seen was that if the full regular season wasn't played, an expanded playoffs wasn't going to happen.
