Hawkeyes2, Andrew was arrested twice at Iowa State not once. KJ gave him two chances to work his way back onto the team. All be it the first time he only had to sit out two duals and be back in time for the Iowa dual. After that didnt work, KJ decided to give him a real punishment. Instead of taking his medicine he bolted for a "new beginning".
It seems as if the change of scenery was all he really needed to get back on the straight and narrow.
