Peyton Manning announced his retirement Monday after 18 seasons in the NFL. That may have overshadowed another NFL retirement, that of the Detroit Lions wide receiver known as Megatron. Everybody thought Maria Sharapova was going to announce her retirement too when she called a press conference this week, only to admit that she had failed a doping test. Plus, the Golden State Warriors break the Chicago Bulls home game winning streak thanks, in part, to star Steph Curry. That and more with The Sklar Brothers.
