Re: Why was JBL nearly looked over?
Well they didn't push him to the top until A) He had that more appealing main event heel persona due to being in a successful tag team for so long and B) Because all their other heels on Smackdown were gone. Lesnar quit, Angle was hurt, Big Show was hurt, and as Heyman said "Triple H didn't want to work tuesdays". It got to a point where they had nothing but a generic Booker T heel run. JBL was just the rabbit they pulled out of their hat and it worked.
Bradshaw had no reason to be pushed before then because they were stacked at the main event scene and he was having a good run with Faarooq as his partner. The JBL character was born out of desperation.
