Reaves is one of the most entertaining players in the league and is a team and fan favourite, so it would be a shame to see him go, but if the Leafs are going to get more offensive contributions from their bottom-six, allowing the likes of Steeves, Tverberg or Minten the opportunity to fill that roster spot would go a long way to creating a more balanced lineup.
Personally, I don't see him going anywhere, given the fact that Craig Berube may enjoy his style of play. That, and the Leafs need someone like him in the lineup at times to help deter the opposition from getting a little too brave.
