The NFL offseason is starting to move towards the summer and that means OTA workouts will soon start turning into mandatory minicamps and after that training camp will begin, setting the stage for the 2013 NFL season.

There are a number of teams that have already started mandatory minicamps, including the Cleveland Browns, Philadelphia Eagles, Green Bay Packers Kansas City Chiefs and New Orleans Saints, who started things off early. The teams are all looking to improve from last season and the Browns, Eagles, Chiefs and Saints will be looking to get to the playoffs, while the Packers want to get back to the Super Bowl after losing a heartbreaking game to the 49ers in the playoffs that saw Colin Kaepernick run wild.

The Cleveland Browns and Kansas City Chiefs have new coaches and staffs to get worked in with their players, as Rob Chudzinski and Andy Reid have taken over after poor seasons the previous year, The Browns fired Pat Shurmur and new owner Jimmy Haslam has brought in a new regime, including GM Mike Lombardi, while the Chiefs have undergone a complete overhaul. Despite going just 2-14 last year, the team is ready to rebound after drafting Eric Fisher number one overall and signing players like Sean Smith and Dunta Robinson while trading for Alex Smith to upgrade at quarterback.

The Eagles also brought in a new coach after firing Reid in Chip Kelly and he is expected to add a whole new offensive element to the equation for the team. Michael Vick is back to start and Kelly is ready to bring his high powered offense to the NFL.
