Practicing situations....

Everything in practice should be tailored to the aspects of a game. Script your scout team sessions with field position, D&D tendencies, and formation keys.

Include sudden change moments during the course of practice, heck don't even tell the AC's.

Create segments that mimic trouble spots for the team: live goal line, D&D situations where the offense is behind the sticks, etc....

Or simply change the routine of practice up: start practice with a live good on good scrimmage session, simply script the objective and keep it short and sweet.

One of the best things we is after we do our dynamic warm up is do a team conditioning/speed/agility circuit and then go STRAIGHT to a live good on good fast paced team passing segment.

Think hard about what the team's comfort zone is and then create a practice scenario that forces them out of that comfort zone.
