Grappling Drills Applicable to Other Sports?

This may sound like an odd question, but I've been asked to run a few conditioning classes for a high school football team. The coach specifically told me that he was aware that the exercises wouldn't be sport specific for football, but he wanted them to develop attributes such as power, coordination, etc, by doing something different than what they had already been doing. He's fully aware that I train in grappling and MMA, and those are the drills that he wants me to do.

I developed a small list so far, but I was wondering if I could get some input from the people here-can anyone help by giving me more ideas on some drills that I can do that would help develop coordination, speed, power, explosiveness, etc?

a couple of exercises that i can think of off the top of my head are burpees, leap frogs, farmer walks, kettle bells workouts...

Penetration steps, Base switches, rolling...

Hindu pushups, handstand pushups, free squats, kettlebell swings, overhead presses

Sit throughs and penetration steps.

as far as grappling being effective for football, this is a topic that is very popular amongst australian rugby league teams atm.
a lot of the top teams have been using top bjj black belts to help with their tackling and grappling training, as the 2 sports can effectively be cross trained.
ill try and get a guy that currently is a trainer for one of the rugby league teams in our national competition to pop his head in and have a talk

Thanks for the help everyone!

WalBJJ, that would be great, thank you!!!

clinch drills for linemen may be good. numerous nfl players use wing chun as a supplementary training method.
