This might be like unrealistic or whatever but I'm not good with offseason plans so like bare with me here lmao.
Explanations
Trade
Jaylen Brown i'd say is a really good fit in Brooklyn with Bridges and all of those guys. He is likely to leave Boston this summer and this is a possible landing spot for him. He can become the 1st option guy next to Bridges and others, so that's good for him. he is on an expiring deal but Brooklyn is a big market team and if he succeeds there he would want to re-sign.
Signings
Fred VanVleet:
If he was to decline his player option, Brooklyn could be a nice landing spot for him. He could bring scoring and the fit next to Bridges and Brown (if traded for) is really good imo. He becomes the 3rd option on whats now a contending team.
Dwight Powell:
Gives more C depth for them, as their current backup C is Day'Ron Sharpe if im not mistaken.
Cam Johnson (resign):
If im not mistaken, he's a RFA so he can be easily re-signed, and he can be a good fit as the nets starting PF next to Clax. He brings shooting to the team alongside FVV and Mikal.
Ideal Starting 5
VanVleet/Brown/Bridges/Johnson/Claxton
Ideal Bench Rotation
Mills/Thomas/O'Neale/Simmons/Powell
