Cavs
DG-Spida-Trey-Herb-Allen is lethal. Losing Mobley sucks but roster is not a title contender as of today. With so much money on payroll, that needs to change. Winning with Spida and Garland requires elite wing play—IMO—and while Mobley is their best defender and it seems antithetical to trade him, a Murphy-Jones-Tyson0Allen-Looney rotation in the frontcourt is an improvement.
Pels
Adding Mobley creates a glut of bigs, but Pelicans need to move forward from their current core (as it hasn't accomplished shit). Getting Mobley to pair with Fears and Queen is excellent. Keep re-building Zion's trade value and swing him for some shooters in the offseason, and New Orleans could actually become competitive in a few years' time.
