Sven Baertschi knows that having the coach's attention is a positive thing.

And whether it's a pat on the back or an on-ice ripping during practice after a drill, it doesn't matter to the 20-year-old Calgary Flames rookie.

"It's the best thing you can have when you have a coach that always helps you and tells you," Baertschi was saying, following another day at the office on Friday. "It's not bad or anything. He sees things and tries to help you. If you do (drills) and he doesn't come over and say anything, maybe you get away with things. You get in that mindset, 'Oh, maybe I did it right.'

"I'd rather have him come over and yell at me and tell me what was wrong than him not say anything."

With the Colorado Avalanche, Flames first-year boss Bob Hartley was part responsible for helping to mould the National Hockey League careers of a young Chris Drury, Milan Hejduk, and current Calgary Flames forward Alex Tanguay.

As such, he understands the adjustment period and the struggles that young players face early on.

Too much pressure, too soon can be overwhelming. Not enough positive reinforcement can damage, leaving a player to second-guess themselves and their abilities.
