It's been a little over a year since San Francisco 49ers star Vernon Davis opened up his own Jamba Juice store—aptly named Vernon Davis' Jamba Juice—in Santa Clara, Calif. A lot can happen in a year. For starters, by signing with athlete-trading platform Fantex, Vernon became one of the first athletes to be traded like stock. (Fantex has since sold all 421,000 shares available—at $10 a share.) The 49ers also were oh-so-close yet again to advancing to the Super Bowl. In this exclusive video interview, Vernon discusses how he and the team have used falling short of their goals as motivation. The always outspoken tight end also talks about the challenges of sticking to a healthy eating plan, and addresses the NFL's ban on post-touchdown goal-post dunks.
