I see this question a lot and get asked it often for articles. It's tough, for me, to compare 10 years ago, as I was in 11-man football. In 11-man, we run mny of the same drills, but with three, sometimes four, times as many kids. So there is way more recovery time for 11-man. I tried to run it the same way last season for my team, and realized they had no time to catch a breath. I didn't let up much, but found ways to maintain the reps, while giving them a chance to breathe. Anyone who played us saw that our team was always in it until the last whistle blew.
