My take, that checkdown was a poor decision for Romo.
He knows there’s only one play left. He knows it’s either down the field or nothing.
Nobody open down the field. Ok. So throw the damn ball away and pack up for half-time.
Why on earth do you checkdown to Choice?! Even if he caught the ball, and ran it, he’s not going to get more than 5-10 yards.
As a Redskins’ fan, it was a brilliant play :-)
