I haven't seen if anybody already touched on this, but when I watched it live - I thought DeMarco was going to score on his breakaway run. .It sure seemed to me that he could have.
Looking at the video, you can see he gets to the outside with Dez out front blocking. Corey Webster has a bad angle and is trailing Murray so the only Giant defenders with a chance to make a stop would have to go through Dez first. Murray has a clear run to the end zone - nothing but daylight in front of him. However, soon after he crosses mid-field, cuts inside - right to Antrel Rolle.
Did he just run out of steam - or was he trying to cutback to avoid Rolle?
