They have had their differences, let's just say that. Ben Groulx is the toughest coach in the Q. Toughest and not even close. He asks a lot of his players. I've known players who hated his guts because he was on their case all the time.
But I know players, Giroux, Talbot and others, that love the guy very much and attribute their pro success to him directly.
In Gatineau, it has become part of folklore that new players get to experience the Groulx factor right from the get go; he runs the most excruciating practices in the league. It has been said that many newly arrived players litterally barf on the ice during their first ever practice with the team because of the hard work asked by the coach.
