#8 Brian Vickers.
Believe it or not, being a complete bust isn’t always a drivers fault. In fact, a particular driver becoming a bust could be due to several outside factors outside of a drivers control Unfortunately for Brian Vickers, who was originally supposed to be a stand out star in The NASCAR Cup Series, he has been repeatedly bogged down by blood clots and unable to stay healthy for any long period of time.
Vickers managed to win three races over the course of his Cup Series career, but his first one was marred by controversy due to the fact that he wrecked two of his teammates to win the race. Vickers then announced that he would be leaving Hendrick Motorsports at the end of 2006 to compete for Red Bull Racing and while he did have some success with the team, all that came to an end in 2011.
That was when Vickers was ruled out for a race at Dover that year due to an unknown medical condition, which later turned out to be a blood clot. It was later announced that Vickers would miss the remainder of the season due to a medical issue. He did manage to return to The Cup Series the next year and finish 25th in points that year, but Red Bull racing was shut down after that.
In the end, Vickers would go on to win two more races in his career before being sidelined again with a hole in his heart and later with another blood clot in his calf. He has raced on and off since being sidelined in 2010 and currently doesn’t have a ride moving forward. He was used in 2016 as a replacement driver for Tony Stewart, but that didn’t parlay into anything else.
