He has won a Cup actually.
If the Oilers had the Leafs record right now, people would be tap dancing up and down Whyte Avenue claiming the glory days are coming back. He's a better GM than anyone we've had since Sather and he has the resume to actually back that up, not getting jobs because he was buds with some higher up.
Lets be real. That guy, like his personality or not, is experienced and knows how to do the job.
With Mac T, we just gotta hope that he can figure out the job (under the genius tutelage of Lowe no less) and not make too many mistakes.
