You have 3 options, get a deeper bench (when I ran FCP back at Nazareth, I played a 10 man rotation and had everyone set to fairly fresh for fatigue), run the Slow Down (but with you playing FB it kind of sounds retarded and counter-productive), or change your offense (I personally would leave the Press alone, it still works in the new engine and it would be easier to switch your FB offense than the FCP defense.
