Just get fast enough to where you can beat the 8-10 year olds in practice and that should allow you to keep up pretty well. My buddies' kid used to talk to me while railing a corner when I first started. I'd be huffing and puffing and he's talking in a normal tone?! Yikes. Eventually my skills progressed enough to where I could outrun him most days. He quieted down then. Now he runs 11X and there's no way I can run with him. Smooth is fast.

Oh, regarding injuries, the guys you go into a corner with have to work tomorrow too. Chances are they're reasonably good at holding their line. Free Agent for $200? It's almost criminal not to get it.
