Based on his one and only MMA fight in K-1, a little bit:
Based on this video, I'd say we know the following:
- His striking is god awful. He has good power (I think), but this video clearly shows his rudimentary footwork and awkward guard position. People don't realize it, but the stand-up game is incredibly complicated and takes a long time to master. 2+ years isn't enough, not even for an athlete of Lesnar's caliber.
- He does look to pass the guard. This is a good sign for Lesnar. He's not content to sit in guard. He actively works for better positioning once the fight hits the floor, a tactic that could easily overwhelm Mir if he's not careful.
- His wrestling is fantastic. We already knew this, but his reflexes in catching Kim's kick and immediate knee-tap takedown are impressive.
- He is aggressive from the outset. Expect Lesnar to close the distance on Mir very quickly and look to put him away with every punch or pass.
