Today marks the first day of the 2015 NFL draft, and football fever has officially swept over Chicago. Team owners, coaches and future pro ballers have all descended on Chicago to make players selections that will shape the league in the seasons to come. The NFL has taken over Chicago's Grant Park, which has temporarily become Draft Town until the draft wraps things up Saturday evening with a performance from American Idol winner Phillip Phillips. Fans will have several opportunities to get autographs from NFL players, dance to live music, check out a Superbowl museum, learn how to play like the pros by taking a football clinic and meet famous NFL team mascots. The best part? No tickets are required to check out Draft Town.
