While Chip Ganassi was enjoying a bottle of milk along with Scott Dixon at Indianapolis on Sunday, his NASCAR teams were at Lowe's Motor Speedway preparing for what would turn into another mediocre run by his trio of Cup teams.

Over in the Cup Series, his operation is in turmoil.

It was only a month ago that Juan Pablo Montoya enjoyed a career-best oval finish of second at Talladega following a crew chief swap with Reed Sorenson. Jimmy Elledge landed with Montoya and Donnie Wingo joined Sorenson.

But last week Elledge was fired by Ganassi against the wishes of Montoya after Elledge reportedly got into a heated argument with Ganassi competition director Steve Hmiel during the All-Star race.

Elledge was replaced by Brian Pattie just days before the 600, Montoya's third crew chief in a five-week period. The two did not get off to a fast start, with Montoya qualifying 47th fastest of 48 cars for the 600.

The race didn't go much better with Montoya finishing 30th. Sorenson finished 22nd and Sterling Marlin, a former Ganassi driver filling in for the injured Dario Franchitti in the 40 car, finished 31st.

Overall, Ganassi's Cup drivers have managed just two top 10s through 12 races, one each by Montoya and Sorenson. In the standings, Montoya, who had climbed into the top 12 after the run at Talladega, has fallen to 17th. Sorenson is 31st, and the 41 team is dangerously close to falling out of the top 35 in owner points. Franchitti's rookie season has been a disaster, and his 40 team is 38th in owner points, meaning that team has no provisionals to fall back on and must qualify for races on speed.

Despite the struggles, Ganassi isn't fazed, saying he does indeed have a plan to get things back on track in NASCAR.

"I feel like we have the right strategy, and I'm staying with that strategy. That strategy works in this company," Ganassi said following his team's Indy 500 victory. "I'm in this business to win races, period. End of story."
