In a change of scenery trade, sure.
Both are facing similar struggles -- low production with fairly sheltered minutes, slightly low puck-luck, but generally take more shots than they give up. As I mentioned with Chytil previously, both should be producing more than their stats currently reflect.
I do think line mates can be a contributing factor for the struggles of both. Chytil's mostly lined up with Gauthier and Laf/Hunt. Zadina has had Fabbri and Suter.
Main concern is that it means one less center option in our organization which is already lacking pretty severely. Chytil has also played nearly double the games.
Personally, I'd lean towards keeping Chytil between the two, though I was a fan of Zadina when he was drafted.
