In short No he can not. IMO he is the greatest fighter of the last 25 years but for me he peaked around 13-14 years ago and as someone said earlier he is a shadow of the shadow of the man he once was. Yes he still has SOME handspeed but his footwork is gone he has no punch resistance and the one thing that people say is the last thing to go has long gone and that is his power. He hasn't starched anyone in real style since Glen Kelly in 2002 but if you watch this video look how much more mobile he is and look at the range of punches he is using really pounding the body and digging in when he throws a punch. He hasn't done any of this really since he came back down from HW. I just wish he had retired when the Tyson fight never materialised!
