The salary cap for 2015-16 is 66.5 mil.
That is supposed to make a huge jump to 89 mil in 2016-17
That is supposed to make a huge jump to 108 mil in 2017-18
This is unprecedented and I believe you need to throw out conventional wisdom. Generally, it's a bad idea to overpay for mild talent upgrades (Detroit signing Charlie V and Ben Gordon is often cited), but there's some big picture stuff at play this year.
Here's a ROUGH look at who has cap space this summer (I grabbed these quick-glance off basketball-reference since I couldn't find a conclusive list anywhere) At quick glance it looks like there are 12 teams this summer with the ability to sign close to a max contract: Philly = 37 mil, Spurs = 33 mil, Knicks = 32 mil, Orlando = 30 mil, Blazers = 27 mil, Celtics = 24 mil, Hawks = 23 mil, Suns = 23 mil, Dallas = 22 mil, Pistons = 21 mil, Bucks = 18 mil, Raptors = 18 mil, Lakers = 18 mil.
Granted, I'm not analyzing these team-by-team. A couple of those teams (like the Blazers, for instance) only have cap space if their star players bail. So their hypothetical cap space is kinda a moot point. But it gives you a rough idea of who Boston is competing with. There's a handful of teams that are real players this Summer. I'd welcome someone to make a more conclusive list of who our competition is this Summer.
Talent attracts other talent. Danny is going to go all-in at the first chance to trade for an impact star, because doomsday is coming. We need to get talent here and we need to get it immediately. Despite the fact we overachieved this year, we lack talent on this roster and we could be right back in the lotto again next year. Generally, stars want to join a team that has a chance to contend. There might not be a single player on this roster that would start on contender. That's a problem when it comes to luring that first free agent.
I say doomsday is coming, because think about how the rising cap is going to impact the league. Yes, Boston will have boatloads of cap space, but so will almost every team in the league. Here's a graphic that illustrates that:
So instead of competing with a handful of teams on the free agent market, we'll be competing with the entire league. That's why free agents might opt to sign 1 year days this year and why teams like Boston should be desperate to lock up any talent they can even if it means overpaying. Come 2016-17, free agents will be able to get paid by any team in the league... so it's going to come down to destination and likeliness to compete. Why would a star free agent join the likes of Jae Crowder and Tyler Zeller on a sub .500 team in Boston when they can get paid the same amount of money to join with Chris Paul and Blake Griffin on a 50+ win team in Los Angeles?
Boston has a lot of things working in it's favor. An awesome fanbase locally and nationally, a great history, fantastic management and a superb young coach for the time being (assuming he doesn't return to College in the next two years like Jalen Rose and Simmons predict). But we absolutely need to get talent on this team THIS summer if we have any chance of competing with the cap boom.
My fear is that the 40 mil cap jump is going to result in super teams. A team like the Lakers could utilize this summer to max out cap space adding Rondo and Kevin Love... then be in great position to add a third star in 2016... and be in even better position to add a fourth star in 2017. The Knicks could position themselves the same way. The rich could get richer. For instance, you could see the Cavs load up with another couple all-stars to pair with LeBron and Kyrie. I've been following this league long enough to see how loaded teams always have the advantage with post-buyout mid-season signings and MLE vet acquisitions. It's going to be the same thing, but instead of adding a veteran on a cheap contract they'll be able to lure additional all-stars.
Which brings me back to my original point. Boston will need to add talent this summer at all costs. If that means giving Greg Monroe max money or throwing stupid cash at Wes Matthews and DeAndre Jordan, it's in our best interest to do it. WHile it would max out our cap space this summer, we'd be looking at an additional 20 mil in 2016 and an additional 20 mil in 2017. Then at least you're trying to lure talent with the likes of established talent like Wes Matthews and DeAndre Jordan on board as opposed to Jonas Jerebko and Gigi Datome.
I'm not going to lose sleep over Boston offering max deals to Middleton or Tobias Harris. Here's an example of how it could pan out for another team. I read recently that Philly is preparing to offer a max deal to 22 year old Harris and they'll be smart to do so. Figure that Philly will end up with someone like Mudiay in this draft. They already have Embiid and Noel as their bigs. Imagine they added Harris at SF and have Mudiay, Wroten, Harris, Noel and Embiid next season. If that team makes a little noise, they head into Summer of 2017 with boatloads of cash to offer to stars. THe Harris signing wouldn't set them back at all. Fwiw, I hear Milwaulkee and Orlando are both prepared to match any offer for Middleton/Harris so it probably doesn't matter.
Gear up for a crazy few years. If DeMarcus Cousins becomes available, be prepared to trade half the team (Marcus Smart included) and craploads of draft picks. Offer max deals to every star on the free agent market. And when all of that fails, be prepared to overpay for a guy like Monta Ellis or Roy Hibbert if either opts out. Gotta have talent to get talent. We absolutely can't afford to play it safe this summer. We need to swing for the fences and gamble. Put ourselves in position to be one of the superteams. 108 mil means you could field a team with 5 guys getting paid 20+ million. You shouldn't bellyache if Boston offers Greg Monroe a max deal.
