I've not heard a thing that even suggests he is looking to leave. Does he want to be a head coach again? I'm sure. But the question boils down to where to start another HC career run, right?
All good choices are going to be "of interest" elsewhere. You cant just go "Oh darn, _____ wants him so we might as well just look somewhere else." With that said, hopefully none of this is necessary and Sark sticks around a few more years.
