If I am Suter, I look at the roster and see if Larsson gets re-signed. If he does, I bank on myself being a much better overall defenceman than Barrie (who I am replacing). If I'm capable of reducing the team's GAA by a margin where the team wins more of those close games (because face it, even at this age, Suter can play 20+ minutes a game effectively), then Edmonton may be a much better team overall.
