Who knows if Gagner will thrive with anyone?
We're talking a kid who basically mailed it in the last two years at Edmonton, then convinced his GM of his new team that he couldn't play in the NHL.
We know he's a defensive liability, which given his size, 5'11 202, screams "no heart" to me, he's not a 170 lb winger with reasonable trepidation about going into corners, he just doesn't want to fight for the puck or do the dirty work.
After 7 years, you usually get what you see, he's not a 21 year old kid who could suddenly break out after struggling for a year or two. Remember Ville Leino? One big season, got paid, went back to his mediocre self. To me that's Gagner's UPSIDE.
Now there's an outside chance he could be a Joffrey Lupul who blossomed in Philly after struggling with bad teams, but Lupul had a better track record than Gagner. (Lupul struggled due to injuries after he left Philly). But I'm not willing to give him a big contract next year even if he puts up 20 goals and 50 points. So to me he's a one year rental.
