Here's a good bit from Shawn Springs, via Peter King:

"You have to play variable forms of bump coverage to have a chance to stop
Terrell Owens. Forget giving him a free release off the line.
So how did Springs drive Owens mad in Dallas? His view: "When I got drafted by Seattle, they picked me because I was a big corner, and the game was evolving to the point where teams wanted big corners to be physical with the big receivers.
"I've checked T.O. so many times over the years, and I've learned a lot. Once he gets his speed up, he's very hard to stop. But he's not as explosive coming off the line as some other guys are. He doesn't think anyone can cover him one-on-one, but in our game-planning last week, [defensive coordinator
Greg]
Blache said, 'We ain't gonna double T.O.' He was giving him to me, one-on-one. He told me, 'I need you this week. We're gonna load up the box [to stop the run], and you got T.O.'
"I loved it. The little waterbug receivers, I can't stay with them. My game is the bigger guys. With T.O., you cannot let him free-release off the line. He will kill you if he gets off the line. Another thing is, you can't play a guy the same way every time. I might stab him one-handed with my inside hand, maybe come back with my other hand [in the five-yard bump zone]. I just try to jam him the first two or three yards. Sometimes he'll bull-rush me. Sometimes he'll try to get away from me. Whatever I do, I try to make some contact with him. That's important. Then I just run with him downfield. There's contact, but it's not interference, it's just two guys going to make a play. And the officials usually let us play.
"Most teams usually come into the game and say, 'We're not gonna let T.O. beat us,' and they do whatever they have to do to try to stop him. But Dallas has so many other ways to beat you. The way to play them is to try to put one guy on T.O., be a little physical, and try to neutralize him.''
