If we got offered Herro, Jaquez, Ware and #13 for Brown, I'd seriously consider.
Wondering what the new-look Celtics team would be:
G: D White, Pritchard
G: T Herro, Baylor
F: (FA), J Walsh, Hugo
F: Tatum, J Jaquez
C: Queta, Ware
That 2nd forward slot alongside Tatum would be a problem.
Jaquez puts up good numbers (15ppg 5rpg 5apg 28mpg) but he is still a poor jump-shooter and a so-so defender. He does his best work off the bench as an undersized PF attacking guys when he has a quickness advantage. He also benefited hugely from Miami's new offensive system with how they pushed the ball and space the floor. No PnRs. Just movement. BOS with their PnR / iso heavy perimeter orientated 3 point heavy offense wouldn't work as well for him.
Note: About 350 of Jaquez' 450 made shots last year came within 10 feet of the rim (78% of his offense). His game is at the rim. Driving to the rim. He doesn't have a reliable jump-shot. That is a dangerous number for a perimeter player. You want to have Giannis level athleticism / Zion level athleticism to make yourself impossible to stop from getting to the rim. Jaquez doesn't have that. He can be stopped. His scoring can be turned off particularly in the playoffs.
K Ware is an interesting young big man who posts strong per minute numbers but his impact is far less than his numbers. He doesn't impact the game defensively much at all despite his size & athleticism. He is largely peripheral on offense despite being a great rim-runner threat and an occasional three point threat. I don't think Ware can beat out Queta for the starting job. I don't think Ware can defend a guy like Embiid. Still, there is potential there. Upside. I am not optimistic about him fulfilling it because his development thus far has been extremely disappointing. I think he ends up more as a journeyman. A few years as a starter. Most of his career off the bench. He could be so much more than that though.
The #13 pick could net a rotation caliber player. A quality bench player to starting caliber player. That could be useful.
Tyler Herro is the main piece in the deal. I like Herro but I like him more as a 3rd option behind JB and JT than a 2nd option. He is a wonderful jump-shooter and solid ball-handler & passer. His poor defense still negates a large chunk of his offensive contributions.
