Watching Frank Mir take extremities to extremes in the highlights before his first match with Brock Lesnar reminded me of watching a couple of world-class jiu-jitsu guys train a few months ago. No point in naming names. But I was impressed by how quickly they conceded submissions when caught. Admittedly, the concessions in this roll were fairly one-sided. But the point of the matter was that it was far more worthwhile for these two top guys to just go ahead and restart and get more training in than it was to waste a lot of time fighting over the penultimate moment before a submission succeeds or fails.
