Jones' comfort level with line 'getting there'

IRVING, Texas -- The Cowboys have mixed and matched their offensive line this summer.

The latest pairings had Tyron Smith, left tackle, Mackenzy Bernadeau left guard, Travis Frederick, center, Doug Free, right guard and Jermey Parnell right tackle. That group might not play in the Week 1 game against the New York Giants on Sept. 8.

So just where is the Cowboys' comfort level with their offensive line?

"It’s getting there," Cowboys executive vice president Stephen Jones said Tuesday. "It’s obviously something that we just started experimenting with last week, so to say you’re just totally comfortable with it, I don’t think anybody realistically would say that. You also have to say, ‘Well, what are the alternatives? Are you more comfortable with this lineup, that lineup or this lineup?’ That’s something obviously Bill (Callahan) and Jason (Garrett) and Frank (Pollack) are really going over in their mind: What gives us the best chance to rush the ball successfully and protect Tony against the Giants."

There is an expectation Ronald Leary will recover from knee surgery in time for the Giants game and start at left guard. If he's not available, the Cowboys will use the first-team line employed in last week's preseason game against the Bengals where Free played at guard for the first time in his career.

"He did a nice job," Jones said of Free. "Parnell coming off an extended injury did a nice job (too). We're looking at ways to get our best players on the field for our best five to beat the Giants."
