With a tweet from Indianapolis Colts owner Jim Irsay, and of course the signing of the dotted line, Andrew Luck officially became a Colt on Thursday.

According to a report from Yahoo! Sports, details of the contract for the 2012 NFL Draft’s overall first pick have not been disclosed, however, it is expected to be similar to the contract signed by 2011 overall first pick, Carolina Panther Cam Newton.

Per Yahoo! Sports:

Terms were not released, but Luck’s deal was expected to be similar to the one signed by Cam Newton a year ago and the one signed this week by Robert Griffin III. Irsay told reporters in April he expected Luck’s contract would be almost identical to the four-year, $22 million deal signed by Newton, last year’s top pick. Griffin signed a four-year contract with the Washington Redskins, a fully guaranteed deal worth $21.1 million, with a club option for a fifth year.

Whatever the details, Colts fans can look forward to seeing Luck behind center this season.

Indy gets a rare opportunity to transition from one star quarterback to another.

Luck threw for 35 touchdowns last season – breaking his school record of 32 in 2010 – and eclipsed John Elway’s career record (77) at Stanford with 80 touchdown passes in only three seasons. He finished with 3,170 yards passing, a 70 percent completion percentage and only nine interceptions without the benefit of an elite wide receiver in 2011. He was the Heisman Trophy runner-up – twice.

Luck has a pretty good idea what to expect beyond wearing a No. 12 jersey for the Colts. He will be expected to help lead the team back from a 2-14 season that included an 0-13 start with Manning out recovering from neck surgery.

It will definitely be exciting to see Andrew play for the Colts this fall! Good luck to him!

And… in honor of the signing… here’s a link to my favorite picture of him! Enjoy!
