Questions like these are always a matter of the criteria. it would seem everyone has a slightly different view/weighting of the criteria, which is ok.
For something like ROH or jersey retirement, things like skill, hero status, and toughness could be considered. I honestly don't think toughness in and of itself should be weighted that highly. It might be something that puts a player over the top but not something that is required at all. Skill and hero status are required, IMO. Skill is obvious. Hero status is determined by a combination of popularity, contribution to franchise defining moments, etc. In other words, how a player makes the fans "feel".
If you look at 3 players, Naslund, Linden, and Burrows, to me it breaks down like this on a 1 to 5 scale for each of skill and hero status.
Linden, skill 4, hero status 5
Naslund, skill 5, hero status 3
Burrows skill 3, hero status 5
Skill is weighted more heavily for jersey retirement. Hero status is weighted more for ROH. Naslund's jersey is retired. Burrows is in the ROH.
I know this is a very simplistic way of looking at things but sometimes it helps to be simple.
By these criteria and rankings I see Gino as a 1 for skill (not saying he didn't have skill, just where he would rank relative to other players) and a 4 for hero status. He should not be in the ROH though I loved watching him play.
