I think people need to realize Muscala and whoever they get from the buyout market are simply 9th-10th men on the roster. Some people seem "disappointed" on social media that we "only" got Muscala but like, we literally don't need another star. All we needed really was some solid depth to get us by the 2nd half of the season and eat up some minutes to give our main guys some rest and avoid fatigue down the stretch.
It's not like these guys are all going to play heavy minutes in the playoffs anyways. And if they are, our chances were probably doomed anyways since it likely meant a few of our stars got injured during the postseason. But playoff rotations are usually down to just 7-8 guys, maybe 9 if a team is very deep.
In theory, the C's definitely have that assuming health
