I think I figured out the lines, guys. Babs is ALL about overcoming adversity and earning the right to feel good about yourself and working your way back up through the lineup, so anytime someone starts playing poorly, Babs gets excited because this is an opportunity for a player to grow, so he demotes them to the third or fourth line. Except Sheahan has been on the club for over a year, now, and hasn't had a poor stretch yet. And Babs is baffled and upset because Sheahan hasn't had that opportunity to build character or whatever. So Babcocks is all "whatever, I'll give you adversity myself! Glendening! Miller! You guys are playing with Sheahan now!" And that's the story of how Mike Babcock saved Sheahan from himself.
I think there's a future for you in sports psychology.....I hear the Maple Leafs could use a man of your skill set.
