Iowa State coach Dan McCarney may make a change in field goal kickers for this week’s game at home against Kansas State. Tony Yelk had two field goals blocked and missed two others in a 24-21 loss at Texas A&M.McCarney says up until Saturday Yelk had performed well in all the different phases of the kicking game he handles.McCarney says the other side of that is the offense needs to finish drives and not just settle for so many field goal attempts. Kansas State coach Bill Snyder says the Cyclones are a quality team. Snyder says Seneca Wallace finds different ways to move the offense.Snyder says it is not just Wallace’s legs that can keep a defense chasing.
