I feel like part of the problem is that the games happen too often and too close to each other
The nfl is a handful of games a week and there's days without football and it gives the media time to FIND narratives and break down plays, and explain what happened, week to week. The nba you got a 1 or 2 day turnaround and by then the next game is coming so the previous one doesn't even matter or register in people's minds. What happened Monday may not happen Wednesday, or Friday. It's a long season where play in October is not the same as Decmeber, not he same at the All Star Break, etc. I think it's more difficult to keep people engaged and care for 82 games. Narratives and players should normally be driving those ratings IMO.
If they wanted the finals to be a bigger spectacle they should have a week off between Conference Finals to let the media dissect and hype up the matchups. There's no other championships in May/June other than Hockey.
My opinion is that he just doesn't mentor them. He probably coaches the fuck out of his players and imparts his wisdom on them but I don't think I've ever seen any articles about Bill being a mentor to his coaches. Or teaching them. He's probably helpful and professional to them and trusts them but I feel like that's pretty much it. Dude is a control freak who wants to be involved in every aspect no?
If you look at Andy Reid, he does seem like a mentor and coach to his coaches, not just his players. Seems like he actively encourages his coaches to move up and get those opportunities to grow. Harbaugh, McDsrmott, and Pederson have all coached for Reid and have done pretty damn well for themselves.
