Jerry Jones was asked by TMZ Sports why he's not interested in signing Johnny Manziel, and he gave a quick, two-word answer: Dak Prescott.
Jones didn't mention any of Manziel's off-field issues, nor did he comment on his prior infatuation with the former Texas A&M quarterback.
Jones is obviously happy with Tony Romo's current backup. One reason why is Prescott, a fourth-round draft pick out of Mississippi State, played like a veteran in a preseason game against Los Angeles last weekend. He completed all but two pass attempts and threw for two touchdowns against the Rams.

Also, Prescott isn't known to wear a disguise while partying in Vegas during the season, so that may be another reason.
