Tyron Smith is getting ready to move

Tyron Smith has met with new offensive line coach Bill Callahan and is starting the process of moving from right to left tackle for the 2012 season.

Smith worked out for a few weeks in Arizona, where he had a good talk with Callahan about any challenges the left tackle position presents.

"I feel like it's a great opportunity," Smith said Friday morning. "It's a blessing and it's going to take a lot of preparation."

Cowboys coach Jason Garrett made it official on Thursday when he said at the scouting combine in Indianapolis that Smith would move to left tackle.

When the Cowboys drafted Smith ninth overall out of USC last year, the goal was to eventually move him to left tackle. But the Cowboys wanted to see how he fared at right tackle, a position that has just as many talented pass rushers coming as the left side.

Smith fared well at right tackle according to the offensive coaches. Left tackle Doug Free's struggles last season allowed the team to make this move now.

"I didn't know what was going on," Smith said. "I just came in and played right tackle. I didn't know if I would be switched over."

Moving Smith to left tackle is just the start of the rebuilding phrase of the offensive line. The Cowboys have some issues with the interior of the line it wants to address either in free agency or the draft. There are some young players on the roster -- including center Phil Costa and guards Bill Nagy, Kevin Kowalski and David Arkin -- to matchup with veteran Kyle Kosier.

Free agents Derrick Dockery and Montrae Holland might not return, but each had bright moments last season.

Getting younger players is a must for the Cowboys offensive line, along with getting the best players in the right spots on the line.

"It's going to be different in some cases because the best pass rusher is on the left side," Smith said. "A little more action."
