If we somehow end up with Marner in the draft which I think is more likely than some think (AZ - Strome, TO -Hanifin, CAR - Provorov?), it wouldn't be a bad idea to have MSL around to tutor him, even if it's just the pre-season and a 9 game stint before being sent back to London. I know Tyler Johnson gives MSL a lot of credit for his development and putting Jagr with the young guys in Florida seemed to do wonders for their games at the end of the season.
Also, as brutal as he just was in the playoffs, MSL did just have a 50 point season. Jagr looked pretty washed up too after the run with Boston.
