INDIANAPOLIS -- The Indianapolis Colts started their OTA's on Tuesday. Players will wear only helmets and they're allowed just six hours of work per day during the 10 OTA's.
The media will be able to watch practice and have access to the players Thursday.
Here's a quick look at five interesting things to pay attention to during the OTA's:
Race for top running back spot: Vick Ballard reminded everybody that he was the Colts' starting running back before a torn ACL cut his second season short. Ballard is in the running with Trent Richardson and Ahmad Bradshaw to be the team's workhorse in the backfield. Richardson is coming off a disappointing first season in Indianapolis and Bradshaw, like Ballard, had his season end early because of an injury (neck). All three will get a chance to carry the ball if things go as envisioned for offensive coordinator Pep Hamilton, but only one of them will carry the bulk of the load.
Reps for Holmes and Luck: This is the time for Colts new starting center Khaled Holmes and quarterback Andrew Luck to work on their continuity. Holmes will try to do something former starter Samson Satele couldn't: Lead the offensive line. "The center-quarterback exchange really starts everything, probably the most elementary fundamental part of a play," Luck said. "I know when you fumble one, it stinks and we pride ourselves on making sure we get 100 percent of those, which we will no matter which center-quarterback combination is in the game."
Replacing Mathis: Suspended linebacker Robert Mathis is able to take part in all of the team's offseason activities, but I wouldn't be surprised if other linebackers, especially Bjoern Werner, get first-time reps. Mathis is allowed to be around the team until his suspension starts in Week 1, but this is the time the Colts need to allow players like Werner to get as many of the snaps with the rest of the starting defensive unit to allow him -- or whoever the starter will be -- to get comfortable. There's no replacing Mathis' 19.5 sacks, but the Colts need to do what they can to at least tread water while their defensive leader is away.
Delano time: Speaking of continuity, this would be a good time for Delano Howell, who has the inside shot at the starting spot, and LaRon Landry to work on their chemistry at safety. But Landry has spent most of the offseason working out on his own like he often does. This is a time, though, for Howell to cement the starting spot since the Colts put their faith in him by not drafting a safety or signing a marquee one during free agency.
