Shane Doan is an athlete, and a competitor. But I think he understands what's coming through the system. I can easily see him, if his speed and play continues through the season as it has started so far, saying enough is enough. He's more than earned a spot somewhere in the organization.
That being said, him being a competitor, I could see him wanting to keep playing. So it's anyone's guess, but I feel he's too involved with this franchise and cares so much about it that he would reflect on this year if it goes down the path it's started in and say "Alright, you could find someone else to replace me, or have someone else come up with the empty roster spot I would give up."
It's a shame too though. I know other fans don't like him, but let's be realistic. He's been with the same franchise his entire career. He's barely sniffed the playoffs, let alone the WCF. The guy is going to be emotional and complain. He wants his team to win, anyone else would do the same thing. So much respect for Doan. If he decides to keep playing, so be it. He's THE Coyote. Everyone in that locker room respects that, and always will.
