The story is Feeley was the third string QB last year because NFL rules dictate the third, or "emergency" QB, can only play when the first two get hurt. Koy Detmer was the holder for the eagles special teams last year, and he would not have been able to fufill this role as holder if he was the emergency QB. This story has some holes in it, it would seem like backup QB is a more important position that holder, but it is plausible.
You're right it has some [big] holes in it. i've argued that point til i was blue in the face. if feeley was the better QB, he would've have been the #2. Detmer is not required to occupy a QB spot simply to be the holder.
