I think my biggest issue is the turnover factor that comes with kickoffs. My good friend George was a wedge breaker and ended up actually playing a year of college ball at Bucknell as a DE because of it; but man, he would sprint as hard as he could and flatten the returner with a clean, shoulder to gut hit. Never injured anybody, but usually knocked the ball loose and gave great field position.
Screw that punt/whatever noise, it's essentially what a pee-wee football team would do, and I seriously wouldn't watch professional football anymore.
