Colts keeping quiet about details for new-look offense

ANDERSON, Ind. (AP) Rob Chudzinski is keeping the Indianapolis Colts' new-look offense top secret.

Andrew Luck is helping out.

As the final week of training camp began at Anderson University on Tuesday, both are revealing little about what to expect. The cancellation of Sunday's preseason opener against Green Bay delayed the fans' first chance to see how things might go on game day.

''Chud certainly has a playbook with different combinations that can beat every type of defense,'' Luck said, referring to his third offensive coordinator in five seasons. ''The offense is designed to attack and beat every style and type of defense.''

This much is clear: Things will be different in 2016.

Indy drafted four offensive linemen in hopes of keeping their star quarterback healthy and off the ground. New quarterbacks coach Brian Schottenheimer is working on Luck's footwork and trying to get him to make throws quicker.

Fans appreciate seeing Luck's baseball slide. Chudzinski, a former tight end who took over as interim offensive coordinator in November following Pep Hamilton's firing, is believed to favor the intermediate passing game and power running.

Nobody knows for sure, of course, and the Colts are unlikely to provide few hints before the Sept. 11 season opener against Detroit.

''Right now we're installing, so every single day is a little bit different and we're doing different things on every single day,'' Chudzinski said last week. ''Once we get through the bulk of our installs, we'll start pulling it together and really refining.''

In some cases, the changes will be less noticeable to the general public.

In addition to promoting Chudzinski and adding Schottenheimer, the Colts brought in former Dolphins head coach Joe Philbin to fix the offensive line, Jemal Singleton to coach running backs and Lee Hull to work with receivers. Philbin has a hands-on approach, something the linemen have embraced.

Chudzinski also plans to take advantage of a new NFL rule that allows coordinators to directly radio plays from the coaches' box to the quarterback. Last season, he relayed the calls to quarterbacks coach Clyde Christensen, who sent them into Luck.

''That's where I've called games from for a variety of reasons,'' Chudzinski said. ''Being on the sideline, there is an advantage in terms of if you can't hear something or if it cuts out, which happens. Things cut out at times and that's a pretty regular type (of) occurrence, and you're close enough to where sometimes you can even yell it out from the sidelines. We have to work through those.''

Chudzinski intends to use the preseason games to iron out the kinks, and there are a few other obstacles.

Rookie center Ryan Kelly, Indy's first-round draft pick, injured his left shoulder during Indy's second practice in full pads. Kelly missed more than a week before returning Tuesday afternoon. Right tackle Joe Reitz is listed as day to day with a groin injury, and Hugh Thornton's chance to compete for the starting right guard job has been derailed by a nagging ankle injury.

Sunday's surprise cancellation added another wrinkle for the Colts, who will now play their first preseason game Aug. 13 at Buffalo.

''We were going to basically treat games one and two as one. We missed out on those snaps in Week 1,'' Pagano said. ''So we'll adjust and go back and look at it and see how this week goes.''

Notes: Pagano said Tuesday that starting defensive end Kendall Langford will miss three to four weeks after having arthroscopic surgery on an injured knee. He hurt the knee in practice last week and was sent for an MRI, which revealed a chondral defect. Pagano did not say which knee Langford hurt. ... Pagano also said defensive lineman Henry Anderson (ACL) and safety Clayton Geathers (foot) are recovering well. Cornerback Tevin Mitchell (hamstring) and receiver Marcus Leak (quadriceps) are all considered day to day. Pagano plans to be cautious with punter Pat McAfee, who hurt his knee in practice last week, too.
