Hard to say, are we thinking if they were the exact player reborn, or if they were the exact player reborn in comparison to their time? Like Dermott would go back 50 years and be the greatest player ever just with his conditioning and skills. Or are we talking about the #1guy in 1920 would be that dominant now?
Either way, names I am surprised no one has said:
Frank Mahovlich - Best LWer to ever play for the Leafs. We are weak at LW, was a ROY winner, his 60-61 season is maybe the most impressive in Leaf history (70 games, 48 goals, 84 points , 131 pims, 21.5% shooting percentage)
Dave Keon - Long time C, a bit small but had a ton of skill and heart. Was tough as nails, Calder, Byng x 2, Smythe in Leafs last Cup win.
Ted Kennedy - Last Leaf to win a MVP. Finished 4 times in the top 5 in MVP voting (all on the Leafs)
Reaching really far back
Dave Pratt, only Leafs D to ever win a MVP award. Probably the best statistical Leafs season by a D, 58 points in a 50 game season. 6'3 D whos career was cut short due to injuries.
