I agree with you on both fighters.
Fury shouldn't fight a lot as a southpaw against wilder and make it ugly on the inside, push your left side against his right side and don't give him space to load up his right.
Both fighters should use body punches, Wilder probably more from the distance to score points, make Fury drop his guard and make him slow down. Fury on the other hand should use more body punches onbthe inside.
Wilder not using feints is a big flaw, that would really add a lot to his game. If Fury switches stance Wilder should try to swarm him right after that, pretty much everyone needs some time to settle in a different stance.
