Dallas Cowboys coach Jason Garrett is no closer to making a decision on the team’s offensive play-caller than he was last week. During a news conference at the NFL Scouting Combine on Friday, he reiterated his statements of a week ago about being confident how it’s going to work out but still working through the mechanics of whether he will call plays or turn the duties over to offensive line coach Bill Callahan. But there was no vacillating from Garrett regarding quarterback Tony Romo and his importance to the Cowboys in 2013 and beyond — so much so that he doesn’t feel pressed to seek a replacement or even draft a quarterback for the future. The Cowboys have had informal contract negotiations with the 32-year-old Romo about a long-term contract extension that will keep him with the team for the rest of his career.  How long that will be is unknown, but Garrett called Romo “a young 32” who has many more years left to play.  “I think Tony’s a young player,” Garrett said. “He’s 32 right now, but if you remember he didn’t play his first three or four years at all, so he’s been a starter for six years and he has a lot of football in front of him. I think if you watch him play you see a guy who can move, a guy who the ball really jumps out of his hand, very spontaneous as a player. You see no signs of him getting old as a player, so we feel good about him for a long time to come.”
