This is an admittedly reductive way to look at it and not the entirety of how I view things, but if AM isn't getting the fandom people around him think he deserves then he probably hasn't hit the levels many of us think he is capable of hitting. And if he doesn't play that well, then him choosing to actually transfer out would be less painful than it seems right now.
I get that it can be painful/infuriating to see a guy want to transfer out, but it's literally happening with ~25% of college players right now. Sure, not all of them are in situations where they seem to have everything at their fingertips, but a good chunk definitely do and you can't be angry at everybody (well you can, but what's the point?). Most importantly, we are operating on asymmetric information here; we don't have the full context for what spurred this action. If he wants to come back, I think we should cut him some slack.
