@nascarcasm: From enemies to co-workers

NASCAR feuds often turn into friendships. Tony Stewart and Kurt Busch had a bad relationship. Clint Bowyer and Michael Waltrip had an on-track spat. Carl and Matt had their differences. Kyle Busy and Martin Truex Jr. had differences before they became teammates. Richard Childress put Kyle in a headlock. They are now team mates. They will drive for Richard in 2023. The saga of Carl, Matt and Brad Keselowski is intriguing. It took place at Roush Fenway Keselsowski Racing. In 2007, Carl left and joined Joe Gibbs Racing, two years later, he joined him.
