Redskins coach Mike Shanahan said Monday he was “embarrassed” by his team’s inability to bring down Patriots tight end Rob Gronkowski on a 49-yard pass play from Tom Brady to Gronkowski early in the game, pointing specifically at the inaction of defensive back DeAngelo Hall.

On the play, two Washington defenders — DeJon Gomes and Reed Doughty — tried to tackle the tight end, but Gronkowski managed to shake them free … as Hall watched.

“That was disappointing because one of the things DeAngelo usually does is finish,” Shanahan said. “A lot of corners don’t like to tackle, but he’s one of the more physical guys in the league.

“I know he was embarrassed by it as was our entire football team. You have to finish when a guy is in bounds because things like that could happen.”

Hall eventually had a hand in bringing down Gronkowski, but only after the tight end had made it all the way down to the Washington 11-yard line. Check out the complete series of screenshots on the play — complete with Hall’s inactivity — here.
