The Cowboys have rocketed to a 4-1 record, fueled in large part by a pair of rookies who have done something no two rookies ever have done in league history.

With 134 rushing yards from running back Ezekiel Elliott and 227 passing yards from quarterback Dak Prescott, the Cowboys have the first two first-year players to rush for 500 or more yards and to pass for 1,000 or more yards in the first five games of a season.

Prescott’s performance will surely increase the chatter that he should continue to play, even after starter Tony Romo’s fractured vertebrate heals. The Cowboys continue to insist that Romo will be back when he’s healthy.

At some point, however, the Cowboys may be tempted to apply a higher bar to the question of whether Romo is healthy.
