Meh, historical Lu Bu's military record wasn't that great. He was a good archer as well as a good enough fighter to beat Guo Si in one of the few commander-vs-commander duels mentioned in the histories, but there's a reason that no one cares about Guo Si. Otherwise, his military record was dominated by losses against better commanders such as Cao Cao and Sun Jian as well as a number of initially successful betrayals that eventually turned to ash.
Oh, and he was good at dodging Dong Zhuo's thrown polearms, but while young Dong Zhuo was supposed to have been a pretty formidable character, old, fat Dong Zhuo was, well, old, fat Dong Zhuo.
