I can not speak to everyone on your list but I can to 4 of the players.
Hossa had 26 goals his final year of playing and was checked out by league doctors in New York and though is seemed fishy I do believe did it' homework.
Zetterberg played 82 games last season bit he rarely if ever practiced and and he had a history of back issues. He has had at least 1 surgery and took time off both during previous seasons and he even had to leave the Olympics early due to back problems.
Pronger is another player who has a history of injuries. Hell he had to take time off due to a puck striking him in the heart. And again their were ba k issues, prior to his calling it quits.
Marelau has zero history of injuries, hell he is an iron man in a sport where players are hurt all the time. You just can no stick him on LTIR because he no longer fits into team plan or costs you in cap. Everyone of the players you listed had to go thru an evaluation by the league in New York.
Fransen is the case that really upsets me, you know nothing of what you are talking about and by using his name you prove to be a dullard. It has been chronicled in local Detroit media and national media of his issues with concussions. It has been stated that he can not leave the bed for weeks on end and he sits in dark room to a oid the head pain. You made yourself look like and idiot, in my eyes when you included his name.
And do not say it is Maple Leaf hatred, if another person would have used Fransen as an example I would be upset with them.
