He should take away from Bogosian. Bogosian has not been that great.Jiricek is not going to take minutes away from Faber, Spurgeon, or even Bogosian, who provides toughness and size that MN needs. Bogo ( a #3 oa pick, mind you), is fine as a 3rd pairing guy. Having said that, I can see Jiricek getting a few NHL games once if gets his defensive game in shape, as sooner or later a RHD will go down.
Ironically, Jiricek's rival for NHL time might be Spacek, who has been playing well. They are both starting to play on the #1 PP in Iowa.
