TPed is a 2 time Funny Car champion and was in the seat for 20 years. I am sure he would have rather had better results his last couple of seasons ... but there are very few that can claim his accomplishments. Plus, he is still getting paid to be in drag racing. I would hardly call that a "whimper".
Jerry Toliver has forgotten more about racing, both on water and on land, than any of us will ever know. He was an excellent salesman for NHRA to non-traditional sponsors. Dale Armstrong was his crew chief, Dale was not going to waste his time on chumps. Oh yeah, he is Art Chrisman's nephew and he has been around the sport in some capacity his whole life. It is not like he parachuted in and then parachuted out.
Whit was legit too. He had a good career in motorsports photography before he ever got in the seat. Ran his own team and was a hell of a paid shoe. Everyone says we need more characters or people who speak their mind in the sport, and that was Whit.
Like others have said, funding dictated all of their circumstances. They were all good for the sport and we definitely need more like them.
