This, admittedly, is as waffling an opinion as there is. But I'll say it anyway.
I don't know what to root for with Garrett. Hope he leaves? Pray he stays and we can nurture him into a head coach someday? I have no clue, honestly.
Mentally, I'm at a point where I feel pretty confident this team needs some major shakeup, yet every major character is set to return next season. So even if Garrett could be good down the road, a part of me wants to root for him to leave for this reason alone. If his exit can help lead to a shakeup here, maybe it's for the better.
I'm just not convinced we can win with Wade, Garrett and this cast of players. So something has to give, even if it takes another organization stepping in and forcing our hand.
