Cup crew chiefs have also been developed from this level. Kyle Busch often uses a developmental crew chief in most of his wins; Dave Rogers and Adam Stevens, two of the current Joe Gibbs Racing crew chiefs at the Sprint Cup level, both used the Xfinity level to move up. Greg Ives was the 2014 Xfinity Series champion crew chief with Chase Elliott before being called up to the Sprint Cup level in 2015 to be Dale Earnhardt Jr.'s crew chief. In some cases, a Cup driver will use a developmental engineer or crew chief, and an Xfinity regular may use an experienced Cup-level engineer.
