I agree with what was said earlier this looks like clickbait and a massive over reaction by fans.
The club let him try out for Toronto so it's not like they are preventing him from ever being promoted.
He's been in the league for a super long time, do you really think he would want to take over a club on extremely short notice, with the most volatile impatient fans, with a team with zero qb for next season, with a team that only won by defense and having the guy who lead that defense leave, with a team that has no depth or canadians, with a team with zero guys at receivers.... why in the hell would he leave a cushy job in Winnipeg for something like that?
If he wants to move on as a HC I think he'd rather go somewhere with a bit of a foundation and time to arrange for his players and coaching staff. Why not work this season and then maybe sign on as the HC for Montreal , Edmonton or maybe the expansion club?
