We head to the Subway SubPrize Party, in celebration of the restaurant chain's 47th birthday, where basketball star Blake Griffin is on hand to make sandwiches for the masses! We chat with him about what would be on HIS signature sandwich, and he tells us a bit about his Subway Dunk Fresh app! He also gives us some dunking tips and tells us how he stays fit during the NBA off-season! Hosted by Nikki Novak (@nikkinovak).
