STILLWATER — For Oklahoma State senior Zac Robinson, there is a wonderful symmetry in Colorado being tonight’s opponent at Boone Pickens Stadium. Robinson’s final college home game is against his home state’s most prominent team, a program that underestimated his quarterback skills coming out of Chatfield High School in Littleton, Colo. A recruit the Buffaloes had penciled in at wide receiver, Robinson will leave as OSU’s most prolific passer and its greatest quarterback. His career numbers say this is so, and so does Cowboys coach Mike Gundy, the man who previously wore the crown as the school’s best-ever behind center. Take Robinson off this year’s depleted OSU roster and today’s 6:30 p.m. contest might have been a nationally televised contest between two 3-7 teams. Alas, despite tonight’s storybook possibilities, Gundy should seriously consider not playing Robinson. If the Cowboys truly are worthy of their No. 12 ranking in this week’s BCS standings, they don’t need Robinson to beat Colorado, which has been deemed a 16½-point underdog. Gundy instead should start Alex Cate at quarterback and have him hand off about 50 times. The Cowboys are back to three solid tailbacks they could rotate. Mix in about a dozen low-risk passes. Shorten the game, get a win and take advantage of your two extra days to prepare for Bedlam in Norman. Robinson’s playing status has been uncertain all week, which is understandable considering the vicious hit he took from cornerback Jamar Wall in last Saturday night’s victory against Texas Tech. Gundy has said he expects Robinson to be available tonight. Robinson could have a concussion, an injury which has become the great unknown in the medical field. There are all sorts of theories on what, and what not, to do with a concussion. The best treatment is an oldie but a goodie — better safe than sorry. A coach erring on the side of caution is always a solid play when it comes to a concussion, particularly when the decision shouldn’t alter the game’s outcome. Tonight’s opponent provides Gundy that opportunity. Colorado’s two Big 12 victories this season have come against Kansas and Texas A&M, who are a combined 3-9 in conference play. Tonight’s game is no gimme putt, but it’s close. Just let someone other than Robinson make the putt. Imagine the horror if Robinson got his bell re-rung tonight and was unavailable at Oklahoma on Nov. 28. If Robinson feels no lingering effects from last week’s collision and those fancy medical tests have shown all is well, by all means let him play out tonight’s wonderful symmetry. But the Cowboys should be good enough to beat the Buffs with the kid from Colorado safely on the sidelines. John Rohde: 475-3099.
