Maybe he's said some things I haven't heard but I've never thought of Hyams as a homer. There are some whose perceptions have become so jaded that anything less than calling for Fulmer's public execution is some sort of de facto homerism.
Hyams stated on the Sports Source back before the GA game he thought Fulmer's odds of coming back were no better than 50/50. Homers don't make that call with 7 games still left on the schedule.
As for the "won't speculate" responses it's so uniform it leads me to believe it's a directive. I won't hold somebody responsible for what they're told from above by an employer. Besides, it's not like they're tricking anybody or being dishonest. I mean, are you saying you have a right to demand speculation from someobdy?
