Yeah, one common theme (from enough different people that it's probably true) does seem to be that there's more youthful energy than in a long time. Which makes sense because most of our coaches have been older except for Garrett, and he was a stuffy 70-year old bitch at heart. Definitely seems like Schotty is trying the Pete Carroll school of thinking.
Not that that's the sole answer -- I'm sure Gus Bradley tried that was in Jacksonville and it didn't work.
Another note, apparently Irvin is a convert now after being so critical before. Not a surprise as we know what a homer Mike is. But he did talk on his podcast about someone getting chewed out for screwing up, so maybe it's not all fun and games.
