I think the plan is probably pretty simple. Turn the Simons salary slot into a starting center making 15-30 million. Something along the lines of Turner, Kessler, Zubac, Stewart, Hartenstein ect. Hope one or two of the Baylor, Walsh, Gonzalez, Minot wing group pops.
Center (7'0+)
Tatum
Young Wing
Brown
White
I think that would be an ideal starting lineup, with the "young wing" ideally being either Walsh/Hugo/Minot who can start as the primary on ball defender to take defensive reps off from White/Brown/Tatum. Personally, I'm dreaming on Hugo being that guy and the team being big and switchable at least 1-4.
Then you have a Pritchard/Hauser as your core bench with Minot/Queta/Boucher all being intriguing as 8-10 guys.
The key is A) What Center do you get? Do you go for a rim protector? A shooter? Somebody switchable? and B) Do you get development from the young guys? If you strike out on all of Walsh/Minot/Hugo/Baylor then you team gets real thin real fast. I'm optimistic on Gonzalez, he just looks like s a guy who will be at least a bench contributor perhaps soonish, but you never know for sure.
The Celtics are in no worse a situation, and in many ways better, of a situation as they were in the summer of 21' when they were fresh of a 36-36 record. The difference is now they KNOW the Jays are a championship level duo. Here's what they did after that:
-Traded a mid-round first (#16) and dead salary in Kemba for Al Horford.
-Traded salary filler in Romeo Langford and late first (#25) along with swap in 28' for Derick White.
-Developed Pritchard (#25 in 2020), Hauser (Undrafted 2021), Kornet (undrafted retread).
-Traded a guy who is always injured in Rob Williams and a guy out of the league in Brogdon, 2024 that ended up #14 first, 2029 unprotected
-Trade Marcus Smart right before he fell apart plus #35 for Porzingis, #25 and another first.
Every one of those deals/avenues above are replicable again, there's no asset they had then that they don't have now other than having 1 less tradeable first. In some ways they are better off because they aren't saddled with a massive dead contract the way they were with Kemba back in 2021.
They need to do things we've already seen them do like find undervalued vets like Horford/White. Develop late firsts/undrafted guys Hauser/Pritchard/Kornet. They won't get everything right; they didn't last time either. They'd probably like the Nesmith/Brogdon trade back for example. But they do have a track record, so in brad we must trust.
