Pit road shakeups for Roush?

Pit road shakeups for Roush? Could there be a few shakeups in the pit crews at Roush Fenway Racing? Officials haven't said anything, but co-owner Jack Roush spent a lot of time in meetings this past week trying to figure out why his teams are having so much trouble on pit road. That usually means changes for the man known as "Cat in the Hat." Carl Edwards went from first to 11th after a crucial mistake on his final pit stop with about 30 laps remaining in Sunday's race at Texas Motor Speedway. Greg Biffle believes pit road mistakes, at least one by him, has cost him a shot at two wins this season. Even Matt Kenseth had problems at Texas. He was second coming onto pit road on lap 252, but left in 15th after a lug nut problem on the right rear tire. Nobody is publicly blaming anybody as Kyle Busch did in a Nationwide Series race last month when a pit road mistake cost him a victory. But there are concerns.(ESPN Insider)(4-10-2009)
UPDATE: Roush Fenway Racing driver Carl Edwards said small changes made this week to his Sprint Cup pit crew were designed to help his #99 team be able to compete for the Cup title this year. Edwards said Friday at Nashville Superspeedway that one crew member was replaced, and a team spokesman said it was front tire changer Corey Quick.(Scene Daily)(4-11-2009)

After seeing Carl give up wins this season, I guess time will have to tell whether not this move will be good for the team or will impact negatively.
