I will never forgive Kelly for making Dayne Crist run all of those designed QB runs in a spread-option manner, and not letting him use that strong arm to make use of a downfield passing game. We had Michael Floyd and TJ Jones as the top two receivers, along with Kyle Rudolph and Tyler Eifert as TE's, and that corps was all but perfect for a downfield passing attack.
In Kiel's case, it was more of a series of injuries that led to a terrible addiction to painkillers. He had a very fine year in 2014, but all of those injuries took their toll to the point where he couldn't get through normal day activities without the painkillers.
To his credit, he went to rehab, got clean, and is living a decent life as a sales rep for Riddell.
