@MikeWellsNFL Do you see the Colts adding any OL, DL, or S depth through FA or trades before the start of training camp? #coltsmail

Mike Wells: Didn't you notice the move the Indianapolis Colts made Wednesday? They signed undrafted free-agent inside linebacker Justin Shirk. There you go. Just joking. Well, sort of. General manager Ryan Grigson is always making roster moves, but all the heavy lifting with the roster is complete. Any roster moves Grigson makes between now and the start of training camp Aug. 1 will be minor, like the one they made in signing Shirk.

@MikeWellsNFL with there finally being some depth in the RB position, who's the likely #2 back for the Colts? #ColtsMail

Wells: It's too early to tell. I think it's probably safe to say, though, that Daniel Herron and Josh Robinson are the two leading candidates to be the primary backup with Zurlon Tipton and Vick Ballard lurking in the water, too. Herron started the final five games, which included the three playoff games, after replacing Trent Richardson last season. Robinson is a promising rookie the Colts selected in the sixth round. Coach Chuck Pagano went as far as to say that Robinson has the potential to be an every-down running back in the NFL. Tipton was moved up to the active roster from the practice squad after Ahmad Bradshaw broke his leg in Week 11. Ballard is the wild card of the group because he's only played one game the past two seasons because of a torn ACL and Achilles. So the backup running back spot won't be sorted out until training camp at the earliest.

@MikeWellsNFL does Zach Kerr have a shot at starting this year? Thought he had a decent rookie year before injury. #coltsmail

Wells: Zach Kerr, who did have a decent rookie season, was a healthy inactive late last season. He was caught in the number's game, as the Colts went with Ricky Jean Francois, Art Jones, Josh Chapman and Montori Hughes as their primary defensive and nose tackles. All indications are it'll be Chapman and Hughes at nose tackle and Kerr will slide over and be given the first opportunity to backup Jones at defensive tackle this season. Kerr told me during offseason workouts that he was getting the majority of his snaps backing up Jones. That said, it's a longshot that Kerr starts unless Jones, who missed seven games with a high-ankle sprain last season, is injured.
