"Coach tells us what we're going to do and we go do it," Chaney said Wednesday.
Dooley said he was playing to win in Tennessee's final possession at its own 39 but after two unsuccessful plays he decided to play more conservatively and let the clock run out.
"That's the way it goes," Chaney said. "We go out and see if we can get something generated. If we made a few plays, we were going to open it up. If we didn't, we were comfortable where we were at."
Defensive line coach John Palermo said his unit had more freedom to chase Mizzou quarterback James Franklin last week, and the results were positive.
"We turned the guys loose and let them rush and not worry about contain," Palermo said. "That really paid off for us. We had the quarterback running a lot during the day, got him off the spot and put some pressure on him. I thought for the most part the kids played good up front."
Senior cornerback Prentiss Waggner quickly regained his starting job after a shaky debut by freshman Daniel Gray, but cornerbacks coach Derrick Ansley said he still expects more from his senior.
"I think any time you get sat down, the coaches are showing you that you need to step up a little bit," Ansley said. "He made a couple plays out there Saturday that put us in position to score. We needed to make more. Any time the ball is up in the air, it's got to be a chance for us to make a play, and not the offense.
"He did well last week, but he could do a lot better because he's got a lot of ability. And we need him in these last two. We need his senior leadership first and foremost, but we also need him to make plays and help us get in winning positions."
Chaney said many of Tennessee's penalties on the offensive line were a result of shifts and movements by Missouri. But none of that should have come as a surprise to players.
"It was a point of emphasis going in, and we didn't handle it very well," Chaney said. "We had several penalties, and several that weren't called. Hopefully, we will get that better."
