Ryan Grigson is flush with cap space, areas of need and options.

The Indianapolis Colts general manager, a self-described grinder, also is levelheaded and deliberate.

So while having more than $43 million in salary-cap space to sign a veteran free agent or three when the market opens Tuesday at 4 p.m., Grigson has made it clear he won’t be mistaken for a shopaholic with wad of cash burning a hole in his pocket.

“It’s a good spot to be in,” he said, “but (we’ll) be vigilant with how we do things.”

One possible bargaining chip can’t be overstated: a player’s history with a certain general manager or head coach.

No one should be surprised if the Colts add another couple of Baltimore Ravens to their roster in the next few days. Speculation is rampant they have pass-rushing linebacker Paul Kruger at the top of their list as Dwight Freeney’s successor. Coach Chuck Pagano was a big fan of cornerback Cary Williams while serving as the Ravens defensive coordinator and secondary coach, and Pagano’s relationship with safety Ed Reed stretches to the University of Miami where he was part of Reed’s recruitment to ‘The U.’
