With the Cowboys, it was too bad that he never was a true blocking fullback, and therefore even with Dorsett, the backfield was never quite as good as the one with Moose Johnston and Emmitt Smith.
On the famous pass play, the Broncos knew the play was coming. Newhouse had a bad habit of not putting in his mouthpiece on passing plays, and, second, he NEVER ran sweeps. So when he got the ball on a sweep without his mouthpiece in, the Broncos immediately knew it was a pass. Richards made an excellent catch---the second superb TD catch that day after the Butch Johnson diving catch (that, under replay, I think would have been disallowed.).
Anyway, thanks Robert Newhouse for countless hours of entertainment as an excellent Cowboy player.
Today it would have been disallowed because he didn't complete the process...but I think according to the rules back then, it was a good catch.
