So it begins for Andrew Luck. The attention. The hype. The expectations. And the prevailing question: What’s next? Sunday Luck and the Indianapolis Colts took their initial steps into training camp with a morning walkthrough and an afternoon non-pads practice at Anderson University. The workout lured several thousand fans and more than a few wore a No. 12 jersey. The focus is understandable and nationwide. Luck was listed prominently in rankings put together by ESPN’s Mel Kiper Jr. and Ron Jaworski. In Kiper’s poll of the NFL’s top 25 players 25 years old and younger Luck 23 is No. 1. “I’m not sure any rookie quarterback faced a bigger challenge” Kiper wrote of Luck’s record-setting 2012. “The future is what pushed him to No. 1 for me and he’ll still qualify for this list 365 days from now.” Jaworski dissected the league’s entire 2013 quarterback class and ranked 1-through-32. Luck checked in at No. 10. “Luck has all the attributes I look for” Jaworski wrote. He pointed to arm strength pocket movement toughness field presence. “I would not be surprised if Luck moved further up my big board after his second season” Jaworski said. “He possesses all the traits necessary to be a very special NFL quarterback.” The Colts used the first overall pick in the 2012 draft on Luck then demanded he perform like a veteran. He carried a heavy load while absorbing heavy abuse. Luck’s 627 pass attempts were the 14th-most in NFL history by any QB. The 41 sacks he absorbed were a Colts’ rookie record and don’t reflect the dozens of times he was hit while throwing.
