Halftime notes from Denver

DENVER -- Random thoughts from halftime where Pittsburgh leads Denver, 10-7:

This is a good ball game. I expect the intensity to continue the rest of the game.

Pittsburgh quarterback Ben Roethlisberger led the Steelers on an impressive touchdown drive to take the lead in the final seconds of the half.

It countered a strong 12-play, 80-yard touchdown drive led by Peyton Manning.

Denver is playing well defensively, even though it did sag some in the final drive of the half.

Manning was 10-of-14 passing for 98 yards in the first quarter. He looks sharp, although he has not been spectacular. But he is efficient.

Two Denver defensive players that are standing out for rookie defensive end Derek Wolfe and free-agent pickup, cornerback Tracy Porter. Both players have made a lot of plays.
