Colts GM 'keeping options open' on center

INDIANAPOLIS -- Not much is known about offensive lineman Donald Thomas when it comes to his time with the Indianapolis Colts.

Thomas didn't make it through two full games last season because of a torn tendon in his quad and a torn bicep.

Turns out Thomas, who the Colts signed to play guard, can play center, too.

It's unknown if he'll ever snap the ball to quarterback Andrew Luck, but it's a possibility for the Colts who have questions at center.

The Colts released last season's starting center, Samson Satele, in March and Phil Costa suddenly retired last month, leaving Khaled Holmes, the likely starter, and Thomas Austin as the centers on the roster.

"If you go through most rosters and depth charts, you usually will have, generally, your starting center, your more true center, so to speak," Colts general manager Ryan Grigson said. "Then, you’ll have usually a guard who can snap, or a guy who’s a guard first that can also snap and play at a winning level as your second center. We have three snappers now. We’ll keep our options open.

"Like all position groups, it doesn’t matter who you are or where you came from, we’ve been pretty consistent, the best players play. Whoever is going to start for this team in 2014 has to produce and play at a winning level week in and week out, period.”

Grigson, like he's done from the start, maintains high hopes for Holmes despite the former fourth-round pick only playing 12 snaps as a rookie at a position where the Colts had problems last season.

"We obviously have plans for him, but again, you have to compete and you have to win a job," Grigson said. "You’re not just going to settle into a job for being average, mediocre or adequate. You have to play at a winning level and ascend to a championship level."
