Given the way he plays with 100% all the time on the ice, Chris Tanev was likely to do that, but now, he's sped up the process, as he has already ingratiated himself in the community, taking part in Leafs Hockey School Skate, signing autographs and getting to know the fans in attendance.
During his time in Calgary, Tanev was a staple of the community and became beloved by the entire fanbase, and given how desperate Toronto have been for a player exactly like him, this makes the pickup even better for the Maple Leafs.
It's certainly a good move for Tanev too, as he now gets to play for the team he grew up cheering for, and as time goes on, the fans are guaranteed to fall more and more in love with him.
