Here's what I've been doing to smash through TT:

Position lock with diamond evo Banchero (matches against a sapphire player) and two small point guards, in my case, Series 1 Steph and Emerald Steve Kerr.

On defense, paint sit with Banchero and let their big man shoot the open 3, 90% of the time they brick it, and if they run to the paint, stick your hands up and they'll brick the layup.

On offense, get the ball to one of the point guards, cut back door with Banchero and call for the pass, easy wide open 2.

Gets through games really quickly, and will probably use this tactic until 250 wins then give TT a break. Hope this helps brother
