Here's an older video of GSP training wrestling with Nate Marquardt from 2010. It's awesome to see GSP looking human while working the over and under position, front head locks, snatch single legs, and high crotches. At the end of the video there are a few rounds of live gos that shows them exchanging takedowns. You can't be afraid to put on a "white belt" and step out of your comfort zone. And that's one thing GSP is known for, being able to have an open mind and learn new techniques.
