Nothing against Phil Costa, but there's a reason the Cowboys panicked and drafted Travis Frederick in the first round of the 2013 draft. Costa is a decent depth player, but he's not somebody that you want as your starting center. Meanwhile, the team still has Khaled Holmes, a fourth-round pick in 2013, waiting in the wings.
The team seems at peace with those two battling it out for the starting position, opting not to go after one of the free-agent starters available on the market.
It's an odd choice, given the value on the market this offseason. Cleveland's Alex Mack was the headliner, but Evan Dietrich-Smith and Brian de la Puente were both reliable starters as well.
Dietrich-Smith finished 2013 with a plus-12.1 grade from Pro Football Focus and signed a four-year, $14 million contract with virtually no risk. De la Puente has PFF's fifth-highest combined grade over the last three years, but was signed by Chicago on a (presumably cheap) one-year deal.
Holmes could end up being the future for Indianapolis, but considering the value available with Dietrich-Smith and De la Puente, some insurance would have been a smart move this offseason.
