Isn't that exactly what a GM is supposed to do ? As with corporations, the best CEO is not the best CFO, COO etc. He is best at keeping things in check, setting strategy, motivating his minions and providing a great PR face. Same thing goes with the Presidency of the country.
And contrary to several opinions on this board, I do see these developments as a significant change - firing of a GM and impending firing of the OC, DC, strength coach. A majority on this board are baying for everyone's blood save Bobby April's. There has to be some continuity and I see these steps as those in the right direction. The only way to blow it is by hiring a crappy OC and DC. For that we all have to reserve judgment.
