The man calling the shots atop the pit box each race is the typically the calming factor for each race team. Part quarterback, part coach and part cheerleader, the crew chief is the glue that holds a race team together and can make all the difference in the world. Usually the calming voice over the radio, it is often their job to calm a frustrated driver and get their head in the game. However, Sunday's Pep Boys Auto 500 saw two crew chiefs in particular losing their cool and having the roles reversed for a few minutes.

Clearly one of the most dominant cars of the afternoon, Bob Osborne called his driver in for service under caution on Lap 111. Carl Edwards led the field to pit road and brought the No. 99 Office Depot Ford to the attention of the Osborne led crew. A bit of a slow stop allowed Roush Fenway Racing teammate Matt Kenseth to beat them off pit road, losing them the lead.

Extremely upset with his team's performance, crew chief Bob Osborne made it clear he did not want to see a stop like that again. "You guys have to do a better job than that," Osborne yelled over the radio. "I don't want to hear it. That was embarrassing!"

Trying to calm the situation and give his guys a boost of confidence, Edwards was quick to cue his radio, calmly saying, "You guys can do it, you're the best on pit road, you can do it."

Angry with losing the lead on pit road, Osborne got on his crew telling them to "stop standing on the wall" and - to put it nicely - go watch the video of the stop to see what they did wrong and make sure it didn't happen again.

Showing just how important track position can be, Osborne blew a fuse over one spot - but when that one spot is for the lead, it's never easy to swallow. Even losing it to a teammate with one of the best over-the-wall crews can leave a crew chief extremely frustrated.

After giving up the lead to pit on Lap 111, Edwards was unable to retake the lead on the race track again until his late-race move around Denny Hamlin on Lap 310. Although he led two laps on pit road - Kenseth had the first pit stall on pit road and gave up the lead each time he came in for service - Edwards went almost two hundred laps without regaining that spot his crew lost in the pits.

Fortunately for Edwards and Osborne, the team and the driver were able to overcome that pit road miscue and take the win. But for Dale Earnhardt Jr. and crew chief Tony Eury Jr., an ill-handling race car late in the run left them frustrated and unsure of what to do.

Early in the race, the No. 88 AMP Energy/National Guard Chevrolet was a rocket ship on a rail around the top of the 1.5-mile speedway. Clicking off fast lap after fast lap, Earnhardt Jr. looked to be a contender once again, only to have the handling go away about halfway through the 500-mile event.

Fighting a loose race car, Eury Jr. made adjustment after adjustment to try and help Dale Jr.'s condition, only to have his cousin call for more changes from the cockpit. With his driver Dale Earnhardt Jr. battling a loose condition, falling through the field and calling for even more changes, crew chief Tony Eury Jr. let his frustration out as he mulled his options planning his stop on Lap 210.

"I can't do anything else," Eury Jr. explained to his driver. Running through a check-list of things the team had already thrown at the car, Eury Jr. finally said, "You tell me what to do. We're out of options."

Making his way to pit road, Dale Jr. simply told his cousin, "You need to calm it down little bit."

The relationship between driver and crew chief can make a world of difference on the race track. Perhaps no relationship is more evident of that than Jimmie Johnson and Chad Knaus. Every week, these two seem to find the magic needed to stay out of trouble and get a great finish. Knaus makes great calls on pit road, while Johnson gets the job done on the track - and both rarely make a mistake.

When things go wrong, how each half of the driver-crew chief equation reacts could mean the difference between taking home the title or being just another "also ran" - something nobody wants to be known as. While it is often the crew chief that has to calm the driver and refocus his frustration, the situations the No. 99 and No. 88 crews found themselves in this weekend at Atlanta show it's not always the drivers that need calming down.
