Intensity up and volume down. Keep your compounds and olympics, if you do them, in the scheme of things. If you take them out and completely revamp what got you to where your at, you'll most likely begin to lose the high level of performance you have achieved in the offseason. Also I would add in balance/core stability training, if not already being implemented. Include proprioceptive stimuli to keep your reaction time and balance on point. Nothing is more important in football, than balance and reaction to various outside stimuli (ie. opposing team's linebacker). I'd Also work in conditioning in the various energy systems, speed, agility and foot work training, if not already being included or covered in practices. Listen to your body as you go, keep the volume down but the intensity high. Save the pr's for the offseason but keep on working. Good luck with your season, enjoy every minute of it.
