They become more comfortable as the season progresses, then in the spring they come back out and don't act like freshmen anymore. Last spring we didn't have a two-minute offense in at all. This year from day one we were functional in a no-huddle offense. We didn't do much of that last year because we were afraid of consistency, but this year I think you will see quite a bit of no-huddle. That's important for a team to find out who those leaders are.
Spring also allows for competition at each position, and competition is a great motivator.
They all want to play. The first spring you are just trying to get them all lined up and learn one position. In the second spring, all of the sudden you can start cross-training guys to play other positions. A guard can play tackle, a tackle can play center, a defensive tackle can play end. We flopped our linebackers and several other positions.
