Must have been on the other board, but I read that doc wasn't worried about the crowd, but constantly making adjustments and focusing on players. Also read there was lots of teaching going on. Thinking I read Peterson was was trying to help correct and improve the throwing motion of qb's during drills. Also heard everyone, players and coaches were very upbeat and excited, and that players were working their tails off which was said to be a lot different from ast years practices, where it seemed players were just going through the motions.
Again, I had to work so I wasn't there, but that's pretty much verbatim what I read on the other board.
