Either way, there is not an issue here (say they do it for Jagr and then do it for Ovechkin and Crosby beer leaguing after retiring a bit..) so ?
Cannot see any issue if they do it for Jagr, cannot see any issue if they don't, it is the most, they can do as they please debate I can think of. There is 0 risk that after they put him in the HHOF he make an nhl comeback that make the situation look strange. There is 0 argument they are better to cool down and take some higher cooler view of his career before deciding and so on.
Nothing bad can come of this either way for us to care I feel like.
