Roush Fenway Racing is rebuilding after what team president Steve Newmark called a "brutal" 2014 that included just two Sprint Cup wins and top driver Carl Edwards bolting for Joe Gibbs Racing at the end of the year.
Although RFR placed two cars in the Chase for the Sprint Cup championship, Newmark said the team fell well short of expectations. Changes were made in the offseason.
Newmark said Wednesday at NASCAR's annual media tour there was a "high level of dissatisfaction" at RFR last season and goals were not met.
Edwards won both Cup races for RFR last season and reached the third round of the Chase before being eliminated. He's been replaced with former Daytona 500 winner Trevor Bayne.
