Nobody in this thread has said that Ryan "screwed Woodhead".
In addition it was the Patriots that gave him an actual chance to play in the NFL, so the concept that Ryan should get some sort of 'credit' for Woodhead is a bit of a reach.
Check.
OT
A twin has told me the two are diametrically different personalities,
this is affirmed for me in my neighbor's two boys.
She believes it is the competition for attention from the parents
that leads to, generally, one quiet, reserved, not expecting or demanding much,
the other, decidedly not that.
Add to this, the parent is Buddy Ryan.
For rex, this constant need for affirmation leads him
to distort almost everything as the reason
for the pat on the back he never got.
It comes across as a emotionally demanding,
perhaps egomaniacal, or unconsciously self centered.
