Do you have max games per position?
If not, and you really want to use the move, I would probably drop Bozak as you'd have more use of a productive second bench D (3 start, 5 bench) than an average bench forward that may not play much at all (11 start, 6 bench).
If you have max games, the only pick up that would be worth it is for another D since you'd need to monitor your games played and too many bench would not be as efficient given it's your only move.
Just curious though, what other defensemen are available on FA? It might give us a better idea whether it's worth a pickup or not.
All I've got...all I've got is insane!
