If he gets 20+ goals, he well have the exact same leverage as Johnsson and Kapanen. Except that unlike Kapanen. he'll be arbitration eligible.
Though I'd presume his age would Be a factor in terms of an arbitration case.
Either way, I dont see this as a problem. The Leafs either see him as a player they want to keep - and do just that or they opt not to sign him.
