I believe Koren's NFL career would have gone differently had it not been for his alcoholism. Even when he was at NC State he had issues. I remember Coach Amato suspending him a few times, and Philip Rivers trying to keep Koren on course. He only played for State for two years since he declared early for the draft. Jerricho Cotchery took his place as the WR1 at State. Jerricho broke a couple records held by Torry Holt, who I'm assuming is your favorite WR of all time. Torry is the best WR NCSU has ever had (at least that I can remember), but my favorite is Jerricho. I loved hearing, "Rivers to Cotchery, Touchdown!" Philip and Jerricho had such great chemistry.
Anyway, I read an article on Koren about three years ago, and at that time he was living in NC, sober, and doing well. I hope he still is sober and well.
