The Indianapolis Colts have told Stanford quarterback Andrew Luck that they will take him with the No. 1 overall pick in the NFL draft, according to a league source.

It's unclear precisely when the Colts informed Luck, but a league source said the team has known for weeks that Luck would be its pick. His style most closely resembles that of former Colts quarterback Peyton Manning, and he is the player Indianapolis wants to rebuild around, the source said.

The Washington Redskins will take Heisman Trophy winner Robert Griffin III with the No. 2 pick in the draft, according to league sources.

With much of the drama seemingly removed from the top two picks, the attention turns to what the Minnesota Vikings will do at No. 3. With multiple needs, they could consider moving down to assemble more picks, or they could start to fill those needs by selecting someone such as USC offensive tackle Matt Kalil to protect young quarterback Christian Ponder.

Colts general manager Ryan Grigson told reporters Wednesday the Colts have a plan for the No. 1 pick, but would not disclose the team's choice.

"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 repeatedly has said the Colts will choose Manning's successor with the top pick, their first No. 1 overall selection in 14 years.
