Worried if Nike has ESPN's announcers in its pocket? I'm not too concerned -- though viewers might be. Seems all of ESPN's "College GameDay" crew -- Chris Fowler, Lee Corso and Kirk Herbstreit -- have deals with Nike for doing speaking engagements on the brand's behalf, and wearing footwear not seen on-air. This is nothing new. A number of network sports personalities, including others at ESPN, have marketing deals.
