Most significant signing: The Colts needed a legitimate cornerback to deal with quarterbacks like Tom Brady and Peyton Manning in the AFC. They had one on the roster last season and they just couldn’t let him go once free agency started. Indianapolis re-signed cornerback Vontae Davis to a four-year, $39 million contract that includes $20 million guaranteed. Now Davis has to live up to the contract and avoid the lapses he had at times last season.
Most significant loss: Safety Antoine Bethea was the backbone of the secondary. He started every game he played during his eight years with the Colts. But Bethea knew there was a good chance he would be playing with another team next season. He signed a four-year deal with San Francisco hours into free agency on March 11.
Biggest surprise: Running back Ahmad Bradshaw was the Colts’ most effective running back last season. His days with the team appeared to be numbered after a neck injury ended his season after Week 3 -- not because the Colts didn’t think he could be effective, but because they already had Trent Richardson and Vick Ballard on the roster. Bradshaw signed a one-year deal to return and hopefully give the Colts three effective running backs next season.
What’s next? The Colts need to find somebody to replace Bethea and start alongside LaRon Landry in the secondary. They also need to finish addressing the interior part of the offensive line. A possible guard isn’t out of the question, and they need to determine whether Cleveland center Alex Mack is worth throwing a lot of money at since the Browns used the transition tag on him, and considering Indianapolis signed center Phil Costa last week.
