When I watch him play and read up on all of his scouting reports, he looks/sounds like a younger version of Johan Franzen, with an added mix of dumb penalties and cheap shots. He gets slapped with with the same inconsistent label, and has all the tools to be a power forward, but doesn't always use them. He also dropped off in the playoffs this season with only 4pts in 13 games.
That being said, I certainly wouldn't complain if he was added to the Red Wings. Never hurts to have another winger with some finishing ability.
Problem is, what would it cost to pry him from the Pens? Part of the reason behind Shero's dismissal is the Penguins inability to draft/develop, leaving them with a lack of strong organizational depth at all positions. I've got to think that they'll be looking for pro-level prospects that are close to contributing at the NHL level. They're potentially losing Niskanen, Orpik and Engelland as UFA's, and the don't seem very high on guys like Despres and Samuelsson, so I wonder if they'll want Sproul or Ouellet (or both?) in exchange. Then again, maybe Almquist could be a valuable trade chip?
