He is trolling us. From my reading these boards, Hostile is a successful person in real life and should know better. Anyone with the most basic leadership experience or skill knows better.
Through my commissioning process for the Army there is one quote which stays with me - "The Army demands results." Bottom line, results matter, success matters. Failure or mediocrity means you messed up. Sometimes it is out of your hands, but if you have control of events and fail to perform it's on you. It's not easy being in a leadership position, I have empathy for Garrett in this regard, however, Garrett's poor decisions cost games. Sugar coat it, rationalize it, distort it any which way, but the record of mediocrity under his leadership bears this out.
As far as the players having faith in him, liking him, who cares. I would rather they respect and produce results for Garrett. I never asked the men I lead if they liked me, or if they thought I was swell, or had faith in me, and none of my commanders ever asked it of me. They displayed through through their performance. Anyone can say nice things, it is what they actually do which defines.
