I'd rather they not have to do an interim coach. But there is not a better interim coaching option than Jim Calhoun I would think. I'd rather not have Chillious be the head coach...
As an aside- It happens in European soccer a bit. They will fire a manager and then bring back the old retired legend until they get a new one.
But obviously a legit head coach is our first option. However, outside of Hurley, it appears to be slim pickings. I'm fine with Calhoun being plan D temporarily, even though it's really not ideal.
