After Colts general manager locked up free agent wide receiver Hakeem Nicks for a one-year, $3.5 million deal, the next question (outside of whether or not Grigson is serious about pursuing Browns center Alex Mack) was:

How much cap space does Indianapolis have left?

The Colts started the new league year with roughly $40 million under the cap. Prior to the new league year starting on March 11th, they inked inside linebacker D'Qwell Jackson to a four-year, $22 million deal. Now, after signing free agents like Nicks and defensive end Arthur Jones - along with re-signing corner back Vontae Davis to a $36 million deal - the Colts have roughly $14 million left to work with if they want to sign (or re-sign) more players.

I'm excluding $3 million from that cap number because that's usually what teams need to keep in reserve to sign their draft picks and make offers to rookie free agents come May.
