Super Bowl kicked off in Miami with a more subdued Media Night Monday that opened with a tribute to Kobe Bryant. The San Francisco 49ers and Kansas City Chiefs have two of their four media sessions out of the way and now can start to focus on practice. Chiefs coach Andy Reid seemed to be enjoying this trip to the Super Bowl far more than his last appearance with the Eagles 15 years ago.    Radio Row was jumping with former players, entertainers and other celebrities in town to talk about the Big Game and more.     Denver Broncos safety Justin Simmons, former Green Bay Packers wide receiver Greg Jennings, Hall of Famer Rod Woodson, and former players Solomon Wilcots and Lofa Tatupu joined Rob Maaddi to discuss various topics ranging from the upcoming game to what they're doing off the field.
