If there’s something different about Dale Earnhardt Jr. this season that might have been lacking in years past, it’s his confidence. He admits that his strong performance during last season’s Chase has provided him with more self-assurance through the first two races of 2014, and it shows with a victory in the Daytona 500 and a runner-up finish at Phoenix. Although he has never won at Las Vegas – the site of Sunday’s KOBALT 400 – he’s finished second there twice. So, fans should expect his confidence to continue.
