He was once known as The Last Emperor which always sounded cool to me.
But maybe this last knock out serves as way to let him know that it could be time to retire even though he can out in 2015 and could considered one of the best of all time which I believe there are only a handful or alittle more of.
I don't know but it looks like he took more shots from his fight with Frank Mir?
Maybe Bader was just stronger? The Heavyweight division is still something they've been working on for a while now so guess we'll just see.
