This deal would NEVER happen. Lets say MIN did decide to trade Towns, which they wont until at least the offseason after this one because he still has three years left on his deal this summer. But if they did they arent going to make another guy with EXACTLY THE SAME LENGTH CONTRACT the centerpiece of the deal because then you have the exact same problem you had with Towns, only with a guy who you didn't draft and feels no connection to your organization.
A Brown for KAT straight up swap makes no sense, really for either team. People need to stop treating him like he's a prospect in these larger star deals. He's not anymore. The Celtics will do everything they can to ADD to him/Tatum before they deal brown, because three stars is how you reach true contender levels.
I disagree with this. Towns is better than Brown and fits better long term with him (since both Brown and Tatum are really at their best playing SF). The team needs a big man.
As for Minnesota, I don't think they'd be looking at a complete reset. They still have Russell and Edwards. They have the potential for another piece from the draft this year. If you add Brown to their roster, I think they'd like that. They need a defensive oriented wing. He is young and still very good. I think he'd be a good fit.
I do agree that Smart doesn't make much sense for Minnesota, but Brown absolutely does. Something like Brown, Nesmith, Wagner, 21 1st, 22 1st for Towns makes a lot of sense for both teams. I might even throw in the 24 1st if needed. If they'd prefer Langford to Nesmith, I'd do that.
Boston next year (bringing back the 3 FA's)
PG - Walker, Pritchard, Edwards
SG - Fournier, Smart, Langford
SF - Tatum, Ojeleye
PF - Towns, G. Williams
C - R. Williams, Thompson, Kornet
Basic Rotation - Walker, Pritchard, Founier, Smart, Langford, Tatum, Towns, R. Williams, Thompson
Use the MLE on a back-up Swing (someone like Morris, not Morris, just that type of player) to be the 10th guy in the normal rotation and then signing someone else for the deep bench (maybe a 2nd round rookie, veteran free agent, etc.)
I think that trade is reasonable for both teams and definitely sets Boston up to actually contend better. I'd look to move Walker for a younger player, even if not quite as good, to further set the team up down the line, but I wouldn't just sell Walker off for whatever I would get, but if I could get someone like Brogdon, I'd do that (even if it cost an additional asset).
