Halftime thoughts: Steelers 10, Bills 3

PITTSBURGH -- Offering some halftime thoughts as the Pittsburgh Steelers lead the Buffalo Bills 10-3:

1. This is the sort of day for defensive football. With wind whipping around Heinz Field, both quarterbacks had issues through the early going. Ben Roethlisberger is 13-for-18 for 125 yards, racking up most of his yards in the second quarter. EJ Manuel is 6-for-13 for 43 yards. He was nearly intercepted on his first pass attempt to Stevie Johnson, but later connected with Johnson for a 23-yard gain.

2. Making his return from a knee injury, Manuel's best play of the game so far was made with his feet. Manuel rushed for a first down on third-and-7, immediately sliding after gaining the necessary yardage. That's something the Bills wanted him to do, and you can bet they were happy about it after that play.

3. Jairus Byrd came up with an interception in the first quarter -- his first of the season -- and returned it 57 yards, but the Bills squandered the good field position. Buffalo continues to struggle in the red zone.

4. The Steelers have given the Bills a bevy of offensive looks so far, mixing in the Wildcat on a few plays. One of those plays -- a direct snap to Le'Veon Bell, who handed off to Emmanuel Sanders -- went for 25 yards. Otherwise, the Steelers have brought on an extra offensive lineman and tried to hammer away with Bell and Jonathan Dwyer. They haven't been overly successful.

5. Bills top cornerback Stephon Gilmore has struggled. He was called for defensive holding and also blew a tackle on the first drive, and was the defender in coverage on Jerricho Cotchery's 5-yard touchdown catch in the second quarter.
