The guy they need to start scratching is Radulov. Maybe sitting him sporadically will give him some burst back because he's looking very old.
In March, Faksa, Glendening, and Raffl each have two points despite never being scratched. Bowness would never consider scratching them because these are your top three PKers, but your PK hasn't exactly been special by recently running at a 78.8% rate in March for 15th in the league.
Also in March, Radulov has three points despite still getting PP time where he's contributing little.
Peterson has three points in March even though he's been scratched a few times and getting little PP time. Not saying I expect a lot from him, but he shouldn't be getting scratched in favor of other dudes who are doing nothing with their ice time.
