We begin in the NFL, and first-round draft prospects Jameis Winston and Marcus Mariota will throw at the annual NFL scouting combine this week. Speculation had mounted that one or both of them would pass on the opportunity, but NFL media insider Ian Rapoport reported today that both will be present. NBA now, and Goran Dragic's representatives told the Phoenix Suns on Tuesday that the star baller will not be re-signing with the team at the end of the season. Across to hockey, and the NHL has been taken to court by a patent troll who claims the league has violated one its patents relating to game broadcasts on wireless devices. And finally, Jason Giambi has retired from Major League Baseball after an incredible 20 seasons in the majors.
