Upon first glance at his numbers, one might not be overly impressed. But there is much more to Larsson’s game than numbers. He is a workhorse, capable of logging major minutes in all situations. He has played with uncommon poise for a player of his age in a league against men in the Swedish Elite League the past two years. Simply put, there aren’t very many holes in Larsson’s game. He is the complete package, capable of taking over a game with his size, skating and elite two-way skills. He’s likely not going to ever contribute elite offensive numbers from the backend, but he is more than capable of rushing the puck end-to-end, making great stretch passes with his superb vision and unleashing a hard and accurate point shot.
Think of Red Wings great Nicklas Lidstrom, who just happens to be the guy that Larsson models his game after, when projecting what Larsson has the potential to become in the not-too-distant future. He has already signed with the Devils and will immediately compete for a job at the NHL level.
