Osweiler may not be the answer, but he has hardly been given a fair shake.
His WR's were dropping easy balls all over the place against the Raiders (that fat contract for DT is looking great, right about now) and he still had a solid outing - he is only single figure starts into his NFL career!
Manning looked done prior to this injury - not just physically done but also mentally - the playoff massacre vs the Colts last year was an absolute sh*tshow that must still live with him, so powerless was he to do anything other than lob floaters down the sideline.
If anything, this year Manning looks worse - it has gotten to the point of seriously affecting his decision making which never used to be a problem (not in the regular season anyway).
In short, bring back PM - but Oz doesn't scare me either.
