Wieden+Kennedy is the agency Super Bowl champ again, writes Andrew McMains, with two spots for Coca-Cola and one for Mondelez International's Oreo cookies this year adding to a big game total of 21 in the past six years. "The greatest challenge for brands and agencies is to not buckle under the pressure. More than ever, it's the time to not overthink it, be courageous and go for it. And I think that's the culture of Wieden+Kennedy," says W+K Creative Director Jason Bagley, a veteran of five Super Bowl spots, and a member of this year's Oreo team.
