Iowa State coach Paul Rhoads announced Wednesday the signing of four junior college transfers.
The list includes the nation's leading junior college tackler, Jordan Harris, along with defensive lineman Gabe Luna, safety Devron Moore and 357-pound guard Wendell Taiese.
Rhoads says all four are enrolled in school and will be available for spring workouts.
Rhoads added that each of them should compete for starting jobs right away.
Three of those signings came on defense, where Iowa State allowed 36 points a game in 2013.
