I'm laughing at some of the negative comments on Twitter about him from C's fans
Obviously Muscala is not Jokic/Embiid, but he is still a very solid backup big that can shoot and can easily give them 10-15 mins a night. Gives Horford/Timelord a little bit of rest down the stretch if he can eat up some minutes. He's also not a pure liability on defense (not elite, but not horrid).
That's one thing we did need. His shooting ability and size (nearly 7 feet) can make him a sneaky good weapon too. Kornet/Griffin were huge for us last night but it won't always be like that when both Horford and Timelord are out (or even just 1 of them).
