The reason for the change is said to be that the team thinks that part of Busch’s success has been his ability to deal with the double-file restarts, aggressive endings, and green-white-checkered finishes. They think that Dickerson has been a large part of that.

They were happy with McGlamery, but felt like Dickerson was too good to pass up. McGlamery will move to another role with the company.

Dickerson was slated to leave Joe Gibbs Racing at the end of this season. So JGR decided to make the change  last weekend, with Eddie D’Hondt spotting for Busch on an interim basis.

Dickerson has been with Busch since 2005, when the young driver was at Hendrick Motorsports. Dickerson eventually became Busch’s agent and business manager until the position was moved to someone else before the start of this season.

Also, Hendrick Motorsports announced the promotion of Marshall Carlson to president and chief operating officer of the organization, a position held by Rick Hendrick’s late brother John that has remained vacant since his passing in 2004.
