JBL is a success story.
Between 1996-1999 he did very little of note worthy, apart from re-create the new blackjacks that did nothing, and a NWA North American title match against Double J, sure he had some matches Savio but they weren't all that note worthy (considering Savio had just had some pretty brutal matches Stone Cold in early 1996).
JBL and APA/Acolytes is what broke him out of his shell, the APA never had any classics BUT when you look at the era they were apart from of it's pretty hard to be remembered when you had TLC matches, that said they did wrestle for the tag belts at the RR2000, they did wrestle at the big PPV's and WIN, Summerslam 99, Wrestlemania 17, but they were lost in the shuffle, Edge/Christian the Hardys and Dudleys are the teams mostly remembered in late 90s/early 00s.
In the middle of the Invasion angle we had a Bradshaw run with European title, beat Hurricane Helms on RAW dropped it 8 days later to Christian at Smackdown but the matc never aired for whatever reason. At the time the European belt wasn't note worthy, it had been bounced around for about 8 months between tag partners, Bradshaw winning was a surprise but showed he could win a singles title.
APA did nothing note worthy until No way out 2002 winning a tag team termoil (2nd time they'd won such a match) and some how got screwed out of a one on one tag titles match at Mania x8, brand split APA go each way.
Little known info Bradshaw actually BEAT 1-2-3 BROCK LESNAR in his hometown at a house show in mid 2002, before Brock won King of the ring, pretty gnarly win considering how big Brock was pushed.
Then came the Hardcore title, I always thought Bradshaw could/should of had a longer run and more dominant run with the title, he didn't it was past around so much, even channging the title belt to the european title and swapping stickers for who held the belt, not very good.
2002-2004 again APA rejoined and Bradshaw did nothing, Wrestlemania 20, Ron Simmons gets smashed all weekend and gets himself sacked, Lesnar and Goldberg run out on WWE leaving a gap on Smackdown, Undertaker had returned on a part time scale, and JBL was left hanging, he's a self made millionaire, why not have him play himself? come on the fans hated him, probably was his matches weren't exciting and he needed people to help carry him, still his title run was pretty good, he'd beat Eddie, Undetaker, Big Show, Kurt Angle and Booker T, that is a pretty good list of guys he beat then lost to Cena at Mania 21.
I can't recall JBL doing much in 2005-2006 apart from feud with Batista and job, then move on to Benoit in time for Mania 22, won the US title and set himself up for a match with Rey that JBL politiced to win the World title at Judgement day 06, back issues stopped that and pretty much haunted him since.
2007-2009 IMO was JBL's finest work, even with a bad back, he returned a heel but showed his old style aggressiveness against Jericho and had a VERY good belfast brawl with Finley at Mania 24, and then his feud with Cena with JBL ACTUALLY getting a win, he was 0-5 (Possibly 6) at one point, then his HBK feud, he won the IC title and lost to Rey in 25 seconds, which he wanted to do and retire at Wrestlemania 25, he did and he never looked back, he started his own company up which is doing well, I'm a JBL supporter he's a success story, NO ONE expected him to win the WWE title in April 2004 and by June 2004 he had, that is good booking shockers, his run might of sucked but he went over good guys.
JBL is one of WWE's success stories IMO
