Let's just say the cap does jump to 100 million a couple of seasons. The Celtics still won't have any star players and then won't have the room for multiple max contract players if they lock up stupid money to players like Khris Middleton. It just doesn't make any sense to sign at best a 3rd option to pretty sizeable money when you don't have your 1st or 2nd option. I'm not saying Boston shouldn't do anything, I'm just saying Boston shouldn't be signing Khris Middleton to that kind of contract. It just doesn't make sense given the current talent (or lack thereof) that is on the team. I'd much rather give that money to Greg Monroe, who I think could possibly be a 2nd option, who plays a much more difficult position to fill, and who is just flat out better than a guy like Middleton.
It does make sense so long as you believe he will outplay his contract because then if it comes to it you just trade him to open up room for that second max contract and boom now you have your two max guys, you enjoyed more success than you would have without Middleton and the handful of spots in draft order he cost you should be more than made up by the haul you get for Middleton when you trade him for picks.
Middleton, Harris, and Monroe are all nice pieces who are young and improving and whom will never be looked at, with a 15 mil contract and scoffed at.
I dont think it will ever be difficult to convince a team to take those kind of guys on as salary dumps.
Because these are all players on the upswings of their careers you avoid any risk of a wallace situation.
Middleton, at worst is a lights out 3 pt shooter who can play either wing and defend at an acceptable level. thats probably worth ~12 mil under the new cap. Now what if he doesnt regress on D and he learns to create his own shot and get to the line a bit. What if hes the guy who played the second half of the season for Milwakee? what if hes even better? I mean hes 23, improved every year, and I think Brad is a far better coach then Jason Kidd.
Now you have a 17ppg scorer who you can either use to entice free agents, use as a centerpiece to trade for a star, or trade to clear cap space for the 30 mil max guy.
