There were at minimum two hot steaks off the top of my head last season where Fox was simply unbelievable. Just able to get to the rim at will, blinding speed, the opponents knew it was coming and couldn’t stop it.
Fox's ability to simply destroy an entire team's defensive game plan isn't really up for debate at this point. You can argue pretty much every single thing about him at this point but he's one of maybe 20 or so guys in the league who is capable of just annihilating teams though sheer athletic talent.
It's the question of whether a team can truly contend with him as their first option that seems to be driving this whole discussion but as far as I'm aware absolutely no one out here, not even his staunchest defender, is arguing that so the question then becomes whether you trade him and a bunch of the pieces around him to do a full reset, do a soft reset by sitting him for the season or something like the T-Wolves did with KAT the year they tanked and got Ant-Man, or try going for it now and move future assets and miscellaneous pieces to get that top option to pair with your second/third options in Fox and Haliburton.
If we're trying to win now by trading Fox, it has to be a first option. Period. But I don't see any of those guys available at the moment so that's why i'm saying we should hold on to him UNLESS we're aiming for a rebuild.
