I still cant stand him for the disgusting displays in the 2004 series against the Bruins where even a soccer player would've said "thats too much flopping", but Mike Ribeiro has to be near the top of the list.
He had all the talent in the world, but for some reason decided to adopt an over the top flopping/diving/dont play the game the right way style to his play to the point that its what he's known for. I know, he has his off ice demons too which doesnt help the situation and unfortunately they ultimately ended his career.
793 points in 1093 games is a legit top 6 talent and he never gets credit for it thanks to his antics.
He had 2 years in Dallas where you thought he was getting it and had turned the corner with 83 points in 76 games and 78 in 82, but it was a mirage.
I used to hate his guts as a Canadien, but now I look back and see him as a tragic story
