I still wish him happiness," a third fan posted."Geez they have him going in front of the net. Never did that for the Leaf's," another posted."Easy to look fancy when there’s not a defender out there…… once someone approaches him he reverts to the fetal position………" said one X user."People wanted him out of Toronto - he’s out now and we’ll see how the leafs fare without him," another chimed inBryan Hayes ditches Mitch Marner to choose Jose Bautista in Most Valuable Toronto AthleteDuring a recent TSN Overdrive segment, seasoned sports expert Bryan Hayes chose Jose Bautista over Mitch Marner as the most valuable Toronto athlete in the last 25 years.Hayes cited Bautista's iconic bat flip as a defining playoff moment while noting that Marner lacks a comparable standout playoff moment."This one's going to be tough because, like Bautista's got the bat flip.
