Some, yes. All, no.
Dual meets can probably handle it. Tournaments are the problem.
A few years back (5?), a kid from NC was seriously hurt running into the wall because there was no buffer off the mat. This wasn't using college rules but that would have been even worse.
Now all this having been said, I think using college ob rules might need to be couple with college edge of mat stalling. Probably helps keep kids momentum from running off.
