INDIANAPOLIS – The Indianapolis Colts have decided who to take with the No. 1 draft pick.

They’re just not planning to let the secret out until April 26.

After months of speculation, scouting and scrutinizing, Colts general manager Ryan Grigson finally told reporters Wednesday that the Colts have a plan for their first No. 1 overall selection in 14 years.

“We’ve known for a little while. We’ve done all our due diligence,” Grigson said during a 30-minute news conference. “Unless there’s an unforeseen problem or something like that, we know what we’re doing.”

Team owner Jim Irsay has repeatedly said the team will choose Peyton Manning’s successor, presumably either Stanford’s Andrew Luck or Baylor’s Robert Griffin III, the Heisman Trophy winner. If the Colts take Luck, the Washington Redskins are expected to take Griffin with the second pick next Thursday night.

Grigson would not say whether the Colts have opened negotiations with either player.

The Colts are still trying to figure out where they are in their massive offseason overhaul, too.

Grigson replaced the father-son front office tandem of Bill and Chris Polian in January, then brought in new coach Chuck Pagano to replace the fired Jim Caldwell. Pagano has almost an entirely new staff, and some players have even found new spots for their lockers.

The biggest change is not seeing No. 18 around town.

Manning was released March 7, a move designed to help quicken the rebuilding process, and eventually signed with Denver. Two days later, the Colts cut a handful of other veterans including defensive captains Gary Brackett and Melvin Bullitt, Pro Bowl tight end Dallas Clark and running back Joseph Addai. Longtime center Jeff Saturday, emerging receiver Pierre Garcon and backup tight end Jacob Tamme all left in free agency.

And those who returned, like receiver Reggie Wayne, are still trying to get acclimated to their surroundings.

“My game plan is the same whoever throws the ball – catch and make something happen with it,” Wayne said. “I met Drew Stanton, I know that guy.”

By next week, Wayne will have to introduce himself to another new quarterback.

Until then, he’ll be catching passes from someone else.

“I don’t know his name,” Wayne said when asked about quarterback Trevor Vittatoe. “I know it starts with a V.”

Inside the locker room, players are content to stay out of the great draft debate. Most have only seen Luck or Griffin play in small bits on television, and nobody wanted to debate the merits of how the new quarterback would fit in with a team that is trying to replace Manning and starting almost completely over.
