Forget Weise's salary, it's a wash with Schlemko's. Weise didn't light the world on fire, we know that. He had a total of 5 goals and 11 points in 509 minutes. None of his points came on the PP.
His production is better than Deslauriers and Hudon combined, and it was also better than Agostino's ES production, which was mostly before Dec 15th anyway.
Folin is a guy the Habs players are saying good things about. Should be more useful as a 7th D than Alzner or Schlemko and if he is not great, we can let him go at the end of the season.
This is a low risk trade that has a little chance to be very good, and a very good chance to be a little helpful.
Remember: Schlemko for another year was doing nothing for us but collecting a cheque, and Froese was in the minors and leaving soon anyway.
