I don't think this has been discussed before but awhile back some were wondering about Tyler Leo, an excellent running back from Ankeny. He told one of my sons that he's going to ISU, I think as a preferred walk on. He's in the 6 foot 190 range and a very good all around athlete, so could project as a rb, d-back, or possibly a receiver, and could be an excellent special teams guy. Starting someday is probably a long shot, but you never know what walk ons are going to step up and be big contributors (Jesse Smith). Glad he chose to be a Cyclone.
