If you compare him to Steven Stamkos, he "looked" more talented in some ways, but just compare their best several seasons. I don't think those are close.
I mean, Lecavalier's absolute best season may be better than any of SS's, but I'd imagine Stammer's best five blow away Vinny's best five.
Vinny Lecavalier's 5 best seasons:
2006-7: 82 games - 52g (1st) 108p (3rd) 4th in Hart voting, 2nd All-Star
2007-8: 81 games - 40g (9th) 92p (6th)
2002-3: 80 games - 33g, 78p
2005-6: 80 games - 35g, 75p
Hard to find a fifth season, I guess you could argue 10/11 - 65 games, 25 goals, 54 points.
Steven Stamkos' 5 best seasons:
11-12: 82 games - 60g (1), 97 points (2nd) 2nd in Hart voting, 2nd All-Star
09-10: 82 games - 51g (1), 95 points (5th) 6th in Hart voting
10-11: 82 games - 45g (2), 91 points (5th) 2nd All-Star
12-13: 48 games - 29g (2), 57 points (2), 8th in Hart voting
17-18: 78 games - 27g, 86 points
Fifth season is tough. Some of his injury shortened seasons were really good (13-14 he has 25 goals in 37 games which I believe led the lead in GPG, and 16-17 he was at over a half goal a game as well before he was injured in the 17th game of the season), but that was his only other full season over a point per game.
I don't think this is close. I would say Stamkos' best season surpasses Vinny's (especially when factoring in league scoring post-lockout), but top 5 it isn't close. Stamkos is a HHOF lock while Vinny is likely on the outside looking in.
