FRISCO, Texas -- As Chaz Green looks to see what it takes to play left guard for the Dallas Cowboys, he turns on the tape of last year and studies the man he's replacing, Ronald Leary.
On Sunday, the Cowboys will see Leary, who left for a lucrative free-agent deal with the Denver Broncos, for the first time, although he might not play because of a concussion suffered in the season-opening win over the Los Angeles Chargers.
If he gets the chance to see Leary before the game, Green will offer up a thank you.
