Andrew Luck arrived in New Jersey on Sunday, just four days ahead of the NFL Draft...the event at which he is expected to be the first player chosen by the teams that comprise America’s most popular sport.

And what an arrival at Newark Liberty International it was: four guys asking for autographs and photos. Probably detained Luck for all of three minutes. Security!

Luck’s California-college-guy togs might have contributed to his ability to fly so far beneath the radar that he has been nearly subterranean, but that still doesn’t change the fact that he may be the least-exposed prospective No. 1 draft pick ever.

Meanwhile, the No. 2 pick, Robert Griffin III, is doing ads, and interviews, and autograph shows, and going to Baylor games, and tweeting and being projected for earlier success than Luck.

Luck, well, he can’t get his face on a milk carton. Maybe that’s a good thing, though, given that he’s stepping into shoes vacated by a legend in Indianapolis. Just what has Luck been up to since the combine and his pro day? Tom Moore offered a glimpse. (Hint: it involved study.)

Moore, the Colts’ offensive coordinator when they had Peyton Manning, recently spent time with Luck and, Bob Kravitz of the Indianapolis Star writes, came away impressed.

A couple of months ago, he got a call from Andrew Luck's father, Oliver, himself a former NFL quarterback, asking the self-styled “unemployed” former offensive coordinator to spend some time in the classroom with his son. ... The pair worked together for 3-4 hours a day, five days a week, for three weeks.

Why would the Lucks do this? What did Luck have to gain when he knew he had the No. 1 spot locked up? Nothing, really.

It was just a chance to get better, and to learn from one of the greatest offensive minds the game has known.

“We had old NFL tapes of different teams, and I'd stop the tape and say, ‘Okay, you're at the line of scrimmage, you see the defense doing this, this and this. What are you thinking?’ We'd go over the possibilities, what you should do, what you can't do,” Moore said. “Maybe we would do that on a Monday, then on a Friday, I'd do it again and stop the tape, ‘Okay, what do we want to do here?’ And he'd tell me, ‘We want to look at this and this.’ He had great application and recall from what we'd studied earlier. It's instantaneous.”

Maybe this is the way to go.
