That's the "holding."
And that's the Porter horse-collar (ignored):
Porter's Horse-Color Frame-by-Frame
WASHINGTON, D.C. -- The so-called "horse-collar" tackle, which came under heavy scrutiny from the NFL's powerful competition committee after Dallas Cowboys safety Roy Williams injured four players with the maneuver in 2004, was banned by the league on Tuesday.
Owners voted 27-5 to enact sanctions against the tackle. The dissenting votes were cast by
Dallas, San Francisco, Detroit, New England
and New Orleans. Players who use the horse-collar tackle will now be penalized 15 yards, and could be fined, as well.
"I really hate the fact that the rule is kind of being named for one player," said Atlanta Falcons team president Rich McKay, co-chairman of the competition committee. "Roy Williams is a good player and, according to the rules that existed (in 2004), he didn't do anything that was illegal. We try not to punish one player, but rather to address the future of that kind of tackle. And, as a committee, we were nervous about it."
