Name one that Delvechhio won.
Ok, here's his Wikipedia page summarized down to the reasons he is up there and Shanny won't be. Bolded areas are of particular distinction.
He would go on to excel both at centre and left wing for twenty-two full seasons and parts of two others, and was notable for his spot on the Production line. No player except Nicklas Lidström in NHL history played more games with just the one team. One of the true gentlemen in the game of hockey, he was a three-time winner of the Lady Byng Trophy for combining good sportsmanship with excellence on the ice.
Following his retirement as a player in 1973—having, at the time, played the second most games and with the second highest assist and point totals in league history—
At the time of his retirement, he ranked second in nearly every significant offensive category in Red Wings history behind only Howe. He has since been passed in most of those categories by Steve Yzerman, but only Howe and Lidström have played more games as a Red Wing.
So besides the 3 Lady Byngs and being basically the second greatest non-goaltending Red Wing (behind his linemate Gordie Freakin' Howe) until Yzerman and Lidstrom finished their careers he has no other reason to be up there.
