You don’t have to be a hockey expert to know that one great game doesn’t make a career, but for a young prospect trying to get his feet wet at the NHL level, it certainly doesn’t hurt. Few but the most intrepid Leafs fans would have been familiar with the name Robbie Earl prior to his impressive debut in Saturday’s 4-2 win over the Ottawa Senators. The Leafs called up their 2004 sixth-round draft pick (186th overall) from Toronto’s AHL affiliate earlier in the day to replace suspended forward Nik Antropov.

Joining Earl in the Leafs lineup were Marlies teammates Kris Newbury and Ben Ondurus, who saw their first action of the season on a Toronto team decimated by injuries to five regulars. “I’ve never had a team (lose so many players at once) off the top end of the lineup,” said head coach Paul Maurice of the Leafs injury situation.

With Earl, the team’s fourth-rated prospect, now up with the big club the Leafs are icing four rookies (the others: Anton Stralman, Jiri Tlutsy, and Justin Pogge), trying to keep playoff hopes alive. Without a permanent general manager or a coherent plan for the future, Toronto finds itself at an organizational crossroads: six points separate Toronto from eighth place in the East, but the team is also only six points from last place overall in the NHL.

While the team is trying to forge its identity, like any other rookie, Earl is simply trying to make a name for himself. “There were some nerves there—the Leafs, Toronto, your first game—but I think I found a way to keep the nerves down,” said Earl after the game.

Admittedly, the 22-year-old Chicago native has been pressed into regular duty out of necessity (he had 11 goals and 22 assists in 44 games with the Marlies), but the team will eventually need help from all its young players, even if injuries have forced their hand. “We want [Earl] to soak up the atmosphere,” said Maurice of his young charge. “Regardless of what happens with the rest of his career, whether it lasts 20 years or [a day or a week], this experience only happens once.” It was only one game, but the rookie has adjusted quite well in the battle of Ontario. His skill level was evident in every shift, even if it remains unpolished. On Saturday night he used his speed and shiftiness to irritate Ottawa defenders on the fore-check. His effortless excursions through the neutral zone created some exciting scoring opportunities, contributing to an opening goal by Dominic Moore, garnering him an assist on a nifty behind- the-back pass to Carlo Coliacovo for Toronto’s third goal.

Saturday’s debut had to be a confidence builder for a player that some would argue is hardly lacking it. After being drafted out of Wisconsin in 2004, the MVP of the NCAA Frozen Four Tournament said “The Leafs got a steal” which caused some critics to label him arrogant.

“Do I come across as cocky? Earl asked during one interview. “I’m just really confident and, at this level, that’s what you need.” It’s that self-assurance that will set him apart from the typical rookie. He’s unlikely to back down from a challenge and strives to be the best player on the ice in every shift. Saturday’s performance against Ottawa was only one game, but Earl certainly had people in attendance asking, “Who was that guy?”
