Sweet baby Jesus I hope not. Shogun's been on the decline ever since that first ACL rupture 5-6 years ago. He made up for it by adjusting his game/style and being smart about his fighting (at times) but it looks like time's up for him. Had a great run but he's not beating the bulk of the elite LHW's right now.
Meanwhile aside from the fact that Lyoto is moving down to 185 he looks great.
At this point in time, if they ever met again for a rubber match and Shogun doesn't get the magical time machine to take him back a couple of ACL ruptures ago Shogun will get finished. Not just beat but finished.
He can't do to Lyoto what he did before. He just doesn't look physically capable.
