I am also hoping that something along the lines of the NHL's original proposal of a $10 million gap between floor and ceiling is in the final CBA. $32 - $42 million sounds good to me, and will give every team a very good chance year in year out and yet allow for differences in development stage of various teams, some rebuilding, some shooting for a Cup. Note that I am sure, like in the NFL, those numbers can be played with for a Cup run with signing bonuses and restructuring contracts. This by far would be the best outcome in my book, as otherwise, as has been said above, some owners will no doubt field bare bones teams and pocket any revenue sharing, etc.
One other advantage none have spoken of. Many many teams under a properly run revenue sharing system will be 'givers' some years and 'takers' others. True there are some markets that will always be so large to be amost permanently 'givers' but we are a gate driven league, at least for now. Your team has a stanley cup run you make more, both from increased fan interest in a winning team and the playoff tickets. Out of the playoffs and rebuilding for 3 or 4 years fans decrease and no playoff money. Look at my Pens, only three and four years ago they had payrolls of $32 and $33 million and for a twenty some year run had attendence smack dab in the middle of the pack, approaching 16,000 many years, and over some. The past few years they went into rebuilding, sold off players and attendence naturally dropped. When you are rebuilding your team will likely be a taker, a giver when not, so this effects many more teams in a gate driven environment.
Final point: Tangent to what I said above, I absolutely friggin hate when people are making their lists of teams to get rid of they take a snapshot of this moment and never look at the big picture. Perhaps half on that 'list' you all compile are there because they are in a rebuilding mode, or are new and never yet built up. For whatever reason they are not at this moment at a stage where the fans can be tested while having a winning team. Some, such as my Pens, have a past where the market has been tested with winning teams and sold out many games. So please look at the big picture if I am to take your arguments seriously.
