So how much of a downgrade is Krajicek? Well, last season he had a worse plus/minus (LK/SO), played against weaker competition (LK/SO) and was on the ice for more goals against per sixty minutes of ice time (LK/SO) while playing on a team that gave up far fewer goals on the year. He's far less physical than O'Brien, registering fewer hits (LK/SO) and PIMs per game (LK/SO), and had just slightly more points per game than O'Brien (LK/SO).
Of course, Krajicek does have "upside," but the move seems a bit risky for a team that has given Jamie Heward more than 40 minutes of ice time through two games. Oh well - at least SO'B got some killer frequent flyer miles for the Prague trip.
