Yeah. My worry isn't the new coach. It's the avalanche of Old Culture that has developed over the past 15 years(?), maybe 20. That's a lot of recruit-to-senior cycles. If we do a count on the guys left from the old sad regimes, we acquire hope at how few. But it's way too soon to acquire confidence based on what the OP (meticulously) outlined for us, imo.
Sounds cliche but I'll bet our third year into this regime will look pretty danged good: 8 (or 9) wins? Coach Rhule is trying to remove not just old attitudes and habits, but an atmosphere, a strange atmosphere of some sort that's hard to even define now. I'm sure he knows all that and is proceeding accordingly.
