Seeing Coach Taylor vulnerable
I feel like we are so used to seeing Coach Taylor as a leader, confident, etc. for most of the show while he is the Dillon football coach, so I actually liked seeing him for that short time at TMU. Where he was the newbie, his higher-ups sometimes dismissed him, etc. It added more human depth to his character and made sure he wasn't just the great, all-knowing Coach Taylor the entire show, even though that is largely what he is/what makes the show so good.
