Throughout his life, the Colts owner has struggled with substance abuse. But as recently as late last year, he said that he was not drinking or using any drugs. But that proved to be false last Sunday night when he was pulled over in Indiana and arrested for allegedly driving under the influence. Police also reportedly found a bunch of prescription drugs in his car. Irsay checked himself into a rehab facility a short time later, and it sounds like he's in for another long battle.
