The Facts: The root of the issue is sprinkled within his DNA: Luck is bad at one thing on the football field because he happens to be very, very good at everything else on the football field. Arm strength? Got it. Reading the defense? Among the best. Accuracy? Not a problem. Knowing when to slide? Ummmm. ... Not so much. Which brings us to Wednesday night, Luck's first time playing football at Lucas Oil Stadium since the hit that lacerated his kidney and ended his 2015 season early. Luck bootlegged from the pocket. He raced upfield. He saw a defender closing in. He slid. The crowd erupted in cheers. "He's reluctantly accepting it," said left tackle Anthony Castonzo.

Diehards Line:Castonzo continued: “I think we’ve all been in his ear, like, ‘Dude, when you get out of the pocket, YOU NEED TO SLIDE. ...’” Same goes for Colts management, Colts coaches, even Colts fans. It’s the most important football maneuver any player on this team will make in any game this season. Luck’s health depends on it. The offense depends on it. The franchise depends on it. For Luck, Wednesday falls in line with a credo he’s long believed: Practices should mimic games as much as possible. The more he slides when it doesn’t count, the more he’ll do it when it actually does. “If you throw an interception, you start running after the guy who made the interception,” he said. “If you’re out running, and you’re not near the sideline, you slide.” But as Star staffer Zack Keefer suggests, sliding doesn’t appear natural for Luck and what makes him reckless also makes him great. But you can’t be great if you’re watching from the sideline and Luck appears to be getting it.
