I'll say it again. Let Anthony tee off on anybodies spleen like that. To the point where you desperately dive into his guard just to stop the small end of a baseball bat from whipping into your organs again and maybe catch a breathe. You might fuck up. That being said, Its pretty universal that you don't grab the head while in guard. Some use it as bait. But its a race. If you win, you get side. If you lose, well, someone else gets to wear your belt.
