My friend goes to the gym twice a day for a couple of hours in the offseason. He's not allowed to have a break from his crazy workout routine on weekends by having some beers with his friends?
Making it in the pros - in any sport - is a whole different level. If your mate really knuckled down and dedicated his body to hockey who knows what he might achieve. You don't have to be an alcoholic for booze to derail your career, and it can generally reflect upon your off-ice work ethic in general. As Sir Alex Ferguson, one of the greatest coaches ever, in any sport says "Show me the evidence that beer makes you a better player, and I'll let you drink beer". Many a proffesional sportsman has identified the turning point in their career as the moment they stopped boozing and started looking after their bodies.
It just worries me that in Abdelkader, Smith and Sheahan we have 3 players who we hope to be the cornerstone of our franchise in 5 years that have all had booze related off-ice problems.
Especially in the offseason, I can't see how drinking would affect you any worse then eating fast food or something like that. For all we know this couldve been this guys first time drinking and he didn't know how to hide it so he got busted.
