What's the status of the IBF belt for Khan vs. Garcia?

[Earl-Hickey]

But if one guys has all the governing body belts he is the man at that weight class. Look how Wladimir Klitschko has all of the belts. (except for Vitali's of course.)

I get what you are saying, the truth is though mate we live in a day and age where we just have to make our own jugements.

If Khan wins this one he will be

Ring Magazine Champion
WBA "Super Champion"
WBC Champion

The other belts are:

WBO Championship (vacant)
IBF Championship (held by a disgraced drugs cheat)

nobody would argue against Khan being "the man"

well, the haters will of course, but nobody impartial would.
