Sure Kadri's having a good year.  He's finally figured out how to be an effective player. It took a while; thanks Babcock.  JVR and Bozak are having fine seasons too. But these guys have been on this team for many years. 

Its the rookies who are carrying this team to the playoffs.  Its the rookies who have made the difference. Last year the 3 guys above finished last.

From last to playoffs on the backs of 6 (really 3, maybe 4 if you want to throw Brown in there) rookies.
