I think any more would be over the top. The football players I see in fall baseball look exhausted. I wouldn't add anything to it. And their play often looks a little rough, my guess from the lack of rest.
My opinion on "football strong" through the strength and conditioning I see from my son's high school, it's all about "maxing out" on squats, bench, dead-lift. If a player survives that without getting injured, move to a more plyo-based workout after football.
