AMES, Iowa (AP) — Iowa State has signed three new football players who will enroll next semester and participate in spring ball. Cyclones coach Paul Rhoads says defensive end Cory Morrissey and defensive backs T.J. Mutcherson and Clifford Stokes and defensive end Corey Morrisey have signed to play for Iowa State. Morrissey, a former star at nearby Gilbert High, played last season at Iowa Western and will be a sophomore in 2012. Mutcherson attended Hillsborough Community College in Florida but didn’t play football. The former prep star from Tampa will be a freshman in 2012. Stokes, a junior from Trinity Valley Community College, chose Iowa State over offers from Baylor, Houston, Kansas and Minnesota.
