Honestly, if the Flyers stay in the playoff race this long and it just completely falls apart and losing all of these need-to-win games, I can see the possibility of him being fired. To stay in the race that long, especially with the core of the team being basically healthy all year, things he's said (while saying them without irony as he is fully just as responsible for f***ing up) and then fall out of the playoffs in the last 10 games should be fire-worthy.
I know people say that changing coaches does nothing, but there are a couple things with this. One, Torts has notoriously had a half life with new teams that weren't Tampa Bay. Hell, if anything, he seems to be someone who also scares actually talented people away (see Panarin and Bob). And two, it's much easier to replace the coach, their systems and other coaches around them than it is the whole team. You can't just throw away the whole team and play with nothing. If you do that, you're the SJ Sharks and they are a straight up embarrassment. It's not good for business and not good for money.
Also, new coaches can help revitalize some active interest in the team for those that may have lapsed on the previous coach.
