Penn looks pretty good there, I think KJ is quicker and fights quicker also, plus he flows more, BJ will work the jab and uses more of a basic style, KJ understands the overall striking game more IMO, he has 10 plus boxing and kickboxing matches, he has put the work in a long time, BJ is a freak though
I don't see a LW light will outstrike KJ at this point besides a hail mary KO shot
sidenote: Sorry guys, not trying to hi jack the thread, but I like to hear what Mamba has to say but trying to get him to comment on a non-UFC thread is like pulling teeth these days
