My Wrestling Question.?

I stopped watching wrestling some time ago, but started too once again. anyway, when i did stop JBL was Champion, & i was thinking to myself. "Bradshaw"?? wow wwe must been hard up for a champ. Is this the same guy who was New Blackjack, Member of takers ministry, APA, now he's the champ? Anyway, how did all that come to be, can someone bring me up to date? I also remember him getting KO'd by Bart Gunn!! Clic.
