The 6-foot-1, 203-pound Kelly, a native of Eagle, Idaho, can make plays with his arm and with his feet and is similar in style and stature to Jake Plummer, another Sun Devil great who hailed from the Gem State.
Taylor has just four career pass attemps and he completed all four of them for 31 yards in last season's opener against UC Davis. He also made a brief appearance against Colorado.
