The Indianapolis Colts have told Stanford quarterback Andrew Luck that he will be the No. 1 pick in the NFL Draft next Thursday, according to ESPN.

Although all signs have pointed to Luck going to the Colts for quite some time, General Manager Ryan Grigson had declined to make it official Wednesday when he told reporters that team officials had made up their mind. But ESPN’s Adam Schefter, citing a league source, said that the Colts would take Luck. That, then, would leave Baylor quarterback Robert Griffin III for the Washington Redskins, who have the No. 2 pick.

Grigson was giving up nothing Wednesday, though.

“We've exhausted the process and pretty much made up our mind,” he said of the search for Peyton Manning’s successor. “We feel really good about it. We've known for a little while. We've done all our due diligence. Barring some unforeseen event or problem, we're pretty sure what direction we're going.”

Straight to Luck.

“If you still need to connect the dots,” Indianapolis Star columnist Bob Kravitz wrote , “chances are you need a two-by-four to the side of the head. It doesn't take a mind reader, boys and girls. It's going to be Luck. It's been Luck for a long time.

“As it should be.”
