Why Driver/crew chief relationships are important

In NASCAR, you have to have a good relationship with your crew chief in order to be successful. We've all seen what Jimmie Johnson and Chad Knuas can do together. Steve LeTarte and Jeff Gordon, Joey Logano and Greg Zipadelli, Denny Hamlin and Mike Ford, Kasey Kahne and Kenny Francis. These are some of the more well known driver/crew chief in NASCAR. Most of the time, they get along, but some times, it doesn't go over so well. Rick Hendrick almost split Jimmie and Chad up because they kept fighting. What makes now so different than a few years ago. Jimmie and Chad still yell at each other. As a driver, you HAVE to have faith and trust in your crew chief. How are you two going to work if you don't have either of those? Everybody can say that Jimmie Johnson and Chad Knuas are the best driver/crew chief combo in NASCAR, but they are not. I know they have the 50+ wins and the 5 championships, but they don't quite mesh together as well as a certain driver/crew chief combo. Here's a hint for you. These to have ten wins together, but have recently been separated due to the fact that the driver was release early from his contract. Give up? It's Kasey Kahne and Kenny Francis. These two may not be as successful as Jimmie and Chad, but they have something they don't. Respect for each other. I'm not saying that they don't, I'm saying is that they don't that the relationship that Kasey and Kenny have. When Kasey gets angry, Kenny doesn't yell back. He tries to calm his driver down. You never seen them angry at each other. One driver/crew chief relationship that doesn't work is Dale Earnhardt Jr. and Lance McGrew. Going back to what Kyle Busch said back in 2008 about Rick making Lance Dale's crew chief, "It's always the crew chief, never the driver." In this case, it is the crew chief. From what I have heard, Lance doesn't listen to Dale. They are not meshing. What I think should happen is when Kasey goes to Hendrick Motorsports in 2012 is Kasey should bring Kenny with him as his crew chief of the 5, Alan goes to the 88, and Rick gets rid of Lance completely. Lance is not helping the situation at ALL. You see, driver/crew chief relationships are very important in this sport. (Note: I think Kenny Francis should get a twitter account.)
