Andrew Luck is going to get his. But until the Indianapolis Colts’ newest cornerstone is able to truly cash in as one of the NFL’s rising stars — perhaps not until after the 2016 season — the team will reap the benefits of having its franchise quarterback playing under a contract governed by the rookie wage scale. That means decidedly less cash out of owner Jim Irsay’s coffers for his team’s most influential player. It means a much softer hit against the NFL’s salary cap. Don’t discount the impact of either. “To have that guy under contract under favorable terms for at least four years is so valuable in building your roster and having that ability to add pieces around him,” said Andrew Brandt, president of National Football Post and a vice president with the Green Bay Packers from 1999-2008 who handled player contracts, including those of Brett Favre and Aaron Rodgers. The Colts entered this offseason with approximately $43 million to spend under their adjusted salary cap of $126.5 million. That enabled them to restock their roster with 10 free agents from other teams, a collection that includes seven potential starters and a proven backup quarterback (Matt Hasselbeck). The Colts were able to add an offensive tackle (Gosder Cherilus, $7.5 million), outside linebacker Erik Walden ($3.25 million) and cornerback (Greg Toler, $4.33 million) for the difference in the salary cap hits between Luck ($5 million) and Peyton Manning ($20 million). The difference in the quarterbacks’ salaries will narrow in future seasons. “That’s how it falls right now,” coach Chuck Pagano said. “We’re in a great spot.” Luck’s rookie contract was for four years, with the Colts holding an option for a fifth year. It included a $14.5 million signing bonus and is valued at $22.1 million, all guaranteed. According to the labor agreement, the fifth-year option must be exercised in March 2014 and would pay Luck a ’16 base salary in line with the “transition tag” from the 2015 season. That’s an average of the top 10 QBs, and is a moving target. This season, the transition figure for quarterbacks was $13.1 million
