He at least provides depth. I don't think Julien trusts him defensively yet so he has to earn that playing time. He gets bonus time on the PP. Right now Julien is able to run two defensively strong lines, Danault's & Plekanec's and I don't see how Hudon displaces anybody off them. I would like to see if he could renew some junior chemistry with Drouin, Hudon-Drouin-Galchenyuk would be an interesting line. I think Hudon's lack of production reflects his teammates play more than his own. He did get one good look flying off the wing on Saturday. Maybe with Hemsky/Sherbak the line would be less of a black hole, than with combinations of Mitchell, Rosey and Fraise.
I'd still like to see what Gregoire could do before Deslauriers, he is RH, and a pest, can have the same reverberating effect that Begin brought.
