PHOENIX -- Here’s a checklist of positions the Indianapolis Colts have addressed in the offseason: Running back, receiver, offensive line, defensive line, inside linebacker and one safety position.

But what about the other holes on the roster, Ryan Grigson?

“There can be perceived holes,” the Colts' general manager said. “Just to kind of clarify, it can’t be Christmas every day. There’s not a forever, endless river of cash flowing. We have a plan. We followed it. Say that safety is something that we went after, well, if that’s your number one need and you have player A and he gets above your ceiling where you want to go financially, you’ve got to cut off at this point to walk away and know that you still have that hole. Because if you just go screaming towards that one need, then you lose on player B, C, D, E and F. You can’t have everything.”

The most glaring hole that still needs to be filled for the Colts is at the other safety position opposite of Mike Adams for a couple of reasons. Indianapolis currently doesn’t have a starter at that position and Adams, who signed a two-year deal with the team on March 10, just turned 34 years old. Grigson talked about Winston Guy and Dewey McDonald as in-house possibilities at safety. Stevie Brown, Quintin Demps, Dwight Lowery and Quinton Carter are some of the top remaining free agents available on Bill Polian’s list.

“We’ll find somebody,” coach Chuck Pagano said. “Somebody will separate themselves from the pack, so to speak. There’s still a couple bodies out there in free agency that you can look at and then the draft. Looking at the draft, there’s some guys that are coming out in the draft that are going to be starting for somebody.”

The Colts also continue to have questions at defensive tackle after bypassing the position during the first wave of free agency. Zach Kerr, Montori Hughes, Kelcy Quarles and Jeris Pendleton are the in-house candidates.

The Colts will also use their picks in next month's draft to try to fill some of their holes.

“It gets back to good, old-fashioned development and playing your youth or waiting until another guy shakes free cap-wise or a guy that’s out there for the minimum that you like. And there’s still guys out there that we like,” Grigson said. “So sometimes they just need a chance. That’s the thing I think our coaches do a good job of not having a biased towards a young player because some places no matter how a guy’s practicing or no matter how a guy’s performing day in and day out, there’s a stigma on the young player. The vet’s going to play in front of him just because. That’s something we have to be stewards of to make sure that doesn’t happen.”
