Every Celtic fan is cheering for Grant to play well, succeed, and get paid.
We do critique/debate the performance of Celtic players, coaches, rotations, wins/losses, trades, FA, front office moves, salary cap, RFA, the 15th man, roster spots, two-ways, etc etc etc which is kind of the point of SoSH/MBPC.
Grant is no different. He is the only key player that isn't locked up past this season, so his RFA is of interest. I like Grant a lot (my header is a giveaway) but definitely try not to let that obfuscate what Brad/Zarren are doing in RFA.
You can be a Celtics fan and still criticize different aspects of the team/players, they aren't mutually exclusive.
