Guys like McKegg and Brod and other AHL/NHL tweeners get called up, much to the chagrin of the majority of the fanbase, is cause the "good soldier" mentality. If those guys never get called up to get a few days or weeks of NHL pay then it will get harder to sign those players that help a lot with creating a structured, winning atmosphere in the minors for other young players in the system.
I don't know if it's the right thing or not, but I do know that having a good AHL team helps create a system of good players filling in on the NHL team turning the franchise into a perennial contender. Losing all the time, at any level, doesn't help anyone.
