Winning the offseason never secures a championship, but it can help. Just last season the New England Patriots brought in Darrelle Revis and Brandon Browner to improve their defense, and of course they went on to win the Super Bowl.

So many factors are included. Salary cap space, areas in need of improvement, age of players and the draft. Here we list the five teams who have had the best offseason.

1. Indianapolis Colts

The Colts had a lot of salary cap space available this offseason, and they did what they had to do: They got Andrew Luck some help. Reggie Wayne is no longer on the Indianapolis Colts, but the team signed Andre Johnson from AFC South division rival Houston Texans. Johnson may not be in his prime at 33 years old, but let's keep in mind that last season he had 85 catches for 936 yards. Adding Frank Gore to the 22nd ranked rushing offense will certainly help. The Colts also added Nate Irving and Dwight Lowery to a defense that ranked No. 11 overall last season.

5. Dallas Cowboys

It's kind of weird seeing the Cowboys fly under the radar during the offseason. Usually Jerry Jones is trying to break the bank on a huge big-name free agent type of player. However, the Cowboys played it safe this offseason. The team franchise tagged Dez Bryant, keeping him on the roster, and they saved a lot of money by not giving into DeMarco Murray's demands. With an elite offensive line in place, the Cowboys don't need a star running back. Greg Hardy has his off the field issues, but the Cowboys got a steal for this defensive end because his contract is on a game to game basis.
