You have to believe in at least one thing about Stephen Ross. You know he will habitually do the same things repeatedly.
1. He has fired the GM, but he will inevitably stick it out with the HC. McDaniel will survive the season somehow, and will probably even get an extension as a show of good faith only to be canned sometime mid to late next season or shortly after next season.
2. The interim GM could very well become the GM for years to come without even one good thing to show he deserves it.
3. And if the team doesn't go with the interim GM, this organization will scoop up someone else's assistant GM or a random scout with no GM experience and give that guy a shot for the next decade. BECAUSE nobody is going to want to take over this team with the HC remaining untouchable for the next season.
