Not apropos of anything in particular but it is interesting to me how philosophies about practice have evolved over the decades. Vince Dooley was a proponent of making every practice as much like a game as possible, including tackling to the ground. Players sometimes were lost to an injury as a result but Dooley thought this made them tougher for game situations. If you survived his practice, he thought you would likely survive the game.
When in was in youth league football I cannot remember a single practice that was not a full pad scrimmage and practice was not much different from playing a real game.
Dodd was a proponent of easing into practice, as CPJ stated in the interview. He liked to keep legs fresh and keep guys limber. He especially followed this in practicing for bowl games. He did not want players dinged up from practice.
All of this came up related to a reporter's question about poor tackling form. CPJ's answer, which I am sure everyone heard, pinned it to training and players being harder to tackle today.
Now I am rambling but one other thought comes to mind. A couple of years ago (I forget the details of this) some coach had the best special teams in the country and was asked about it. He responded that they practice special teams just like it is a real game, full speed and full contact. Other coaches when asked said basically, "Are you nuts!"
