I wonder which side is currently more unhappy with the CBA, and what the biggest issues are (outside of the revenue split).
Owners, I think. From what I've read, its an upper spending limit.
It's not that the owners are upset, it's that a hard cap is their
golden goose white whale, and they're going to keep chasing after it every time there's a renegotiation. Rumors from a few weeks ago were that they've pretty much given up again this time around too. For the most part, both sides are relatively happy, because everyone is making a lot of money -- that's why they keep pushing back the opt-out deadline. I think the new CBA will look like the old one. If I had to pick the biggest change, I think the luxury tax tiers will be steeper between steps, but the steps will be wider, and will probably increase in width as the cap increases. Currently every $5 million increase above the tax puts you into a new incremental rate. That $5 million amount went into effect in the 2013-2014 season, but the cap has more than doubled in that time. Every other element of the CBA related to the cap or tax has been adjusted upward since that time. I think you'll see it bump to $10 million for each step, and then continue to rise proportionally to the cap increase every year, but also the penalties with each tier will likely go up too. This will make players happy because more teams will likely be willing to go up to $20 million into the tax (and more if the steps widen every year like I think will happen), but owners happy because there will be a future luxury tax wall that teams won't want to cross because the penalty is just too steep, my guess at around $30 million in present cap terms.
The other major sticking point is undoubtedly how to handle the revenue spike from a future media deal. Do you phase it in before and after the deal, or have a one-time spike when it kicks in?
I know people also talk about the age limit for the draft, but I don't think either side cares strongly about it. Players who've made it into the league would rather there not be more players taking their jobs, and most owners don't want to pay 18 year-olds millions of dollars. This seems like something Adam Silver wants more than anyone else.
