I'm no fan of prevent defense, but if Hayward didn't blow his coverage, it's not likely the 3rd and long pass was completed. Dom had a player in position to make that play, the player simply didn't make it. I don't see how that call specifically can be placed on Dom. He also had many players in position to stop Peterson many times, but they often failed. He can be blamed for the players lack of ability to tackle, but not really the play-calling on those plays. The defense just has to make the plays when in position to do so. They often did not tonight.
EDIT: I tweeted early in the game that Woodson is really missed in a game like this. I am not a fan of MD Jennings as all. Hopefully he will never see the field when Woodson is back.
