Jamie McMurray seemed genuinely excited during the Charlotte Motor Speedway media tour on Thursday about the prospect of having just one teammate in Juan Pablo Montoya at Earnhardt Ganassi Racing. Conventional thinking in NASCAR dictates that bigger is better, especially when it comes to the number of teams in your organization. For McMurray, that clearly wasn`t the case at Roush Fenway Racing. He languished there, failing to meet lofty expectations while finishing no better than 16th in points in any of the past four seasons. Whether McMurray can enjoy the type of success he formerly had with Chip Ganassi – he was on the cusp of making what was then a 10-driver Chase between 2003-05 with points finishes of 13th, 11th and 12th, respectively – remains to be seen at Earnhardt Ganassi Racing. Being paired with Montoya, whom McMurray said dumped him at Bristol last year and triggered a brief spat between the two, could potentially be a benefit given the No. 42 team`s success last season. But the Sprint Cup car`s new spoiler – and how all teams adjust to it, not just those at EGR – could derail the progress made by Montoya last year. There won`t be as much information to draw from, obviously, with a two-car outfit compared to what McMurray had at Roush Fenway Racing. He is more than OK with that, based on his words Thursday, and seemed happy to be moving away from the information overload that occasionally resulted from having so many different voices in play. At 33, this would appear to be McMurray`s last best chance to realize the potential so many – including Jack Roush – saw in him back in 2006 when he was lured away from Ganassi. If he can do it with one teammate at EGR, it would strike a certain blow to the bigger-is-better philosophy.
