And while he didn’t lead the team in rushing either season, just the threat of him running, either in the option or scrambling, helped. "That’s going to change how defenses approach us,” Gundy said. "On a passing down, you can’t just drop everybody out of there and cover the receivers, because he’ll pull the ball down and run it.” Gundy would just like him to not only tuck, but duck sometimes. Robinson’s teammates, too. "When Zac takes off running,” said cornerback Perrish Cox, "it’s like, ‘Yes… but get down!’” For the most part, Robinson has proven durable. He’s played in all 26 games the past two years. Still, he’s taken some shots. Robinson suffered a concussion in the fourth quarter at Texas A&M in 2007 and couldn’t finish a tight loss to the Aggies. Last year in the Holiday Bowl, he suffered a shoulder injury while scrambling and struggled to throw in the final quarter of a loss to Oregon. This year, Robinson may be better built for taking on defenders. He’s stouter than ever, weighing a solid 220 pounds. And neither he, nor Gundy, is interested in altering the offense, even if Gundy would prefer Robinson alter his approach. "At some point, you become like a 12-year vet in the NFL,” Gundy said. "You’ve proven to everybody. And you can take the Franco Harris deal and just step out of bounds and protect yourself. "I think he’s earned the right to do that. I don’t know if he will or not, but I’d certainly hope he would.” Not likely, since Robinson relishes the hits rather than resists them. "I honestly feel pretty good after games,” Robinson said. "My body has been through a lot. There are games where I’ve had quite a few carries and some where I don’t. So it hasn’t been too bad. "I’m weighing 220 now. So hopefully those hits, it’ll help me out in that regard.” Text "Cowboys” to 65360 today for your chance to win 2 tickets to OSU vs. Georgia in Stillwater, Sept. 5.
