An interesting idea, might be worth a shot to get Lupul going again. He and Kessel had great chemistry at one point too.
It's tough to split up lines like JVR-Bozak-Kessel that are doing so well though.
When Bolland gets back, how about:
JVR-Bozak-Clarkson
Lupul-Kadri-Kessel
Holland-Bolland-Kulemin
Raymond-McClement-Orr
Theoretically, you could swap Holland for Kadri. Or, to get Kadri going again, maybe have Holland with Lupul-Kessel and Kadri with JVR-Bozak?
Anyway, about Bozak, I've always been a fan of his. I still don't think he's a #1 center, but he's having a fantastic season thus far. Very useful player.
Bozak/Bolland seems like an excellent 2/3 combo down the middle. Now we just need a #1. (Please, Kadri? Go wizard?)
