Yes AND no. I love the idea of the way practice is ran, but it is something that is more a product of the new CBA than anything else. While it is true that you get many more plays which is very important now with the cut down practice periods, there are also some negatives. Players can't be corrected until after practice. Before when you had more time between plays, positions coaches would have time to take players in their group aside and explain things play by play. Now young players who are learning whole new concepts have to practice mistakes for a whole day before they get them corrected.
This new system will work great for vets who already know most of what they need to learn, it is also great for conditioning and has it's merits for QBs who need to learn to read defenses as quickly as possible. It will help the offense get used to the speed the coaches want to play at to keep defenses from substituting and taking advantage of mismatches. But players like Les Brown will have a very hard time learning at this pace. Humans need time to process information. Although I do love the idea there are times when they also need to run it at a slower pace IMO. One thing is for sure, you WON'T be seeing other teams copy it THIS year. There is a lot more to it than just speeding up practice. It's not just something you can change in the middle of a TC.
The intangibles are what makes it so useful. Since RT already knew the system it gives him a great chance to see things at a more game speed. It also dictates what the defenses can do which is also great for RT and the rest of the QBs. But if RT had came from another college system it would have made it much harder for him to get up to speed.
Humans learn at different speeds, and for some it will be the greatest things since sliced bread, but for others who learn slower or have more to learn, it may become VERY frustrating IMO.
