Halftime observations from Bills-Patriots

Posted by ESPN.com's Tim Graham

FOXBOROUGH, Mass. -- It sure is quiet here in Gillette Stadium.

Buffalo Bills defensive end Aaron Schobel intercepted a Tom Brady screen pass and returned it 26 yards for a touchdown to give Buffalo a 14-7 lead over the New England Patriots late in the second quarter.

The Patriots drove down the field for a 20-yard field goal at the half, but few could have thought the Bills would be leading in the third quarter.

The Bills haven't been dazzling, but they've been doing enough to make things uncomfortable for Patriot Nation.

A few notes and observations so far:

Brady's stat line: 13 of 22 for 159 yards, no touchdowns, one interception.

Trent Edwards' stat line: 7 of 11 for 65 yards and one touchdown.

Reigning defensive rookie of the year Jerod Mayo is out. The tackling machine went down with a knee injury in the first quarter. His return has been announced as questionable. Gary Guyton has replaced him.

Terrell Owens has been a non-factor. Zero catches.

Bills left tackle Demetrius Bell has made some silly mistakes. The Bills have been whistled twice for illegal formation because Bell wasn't on the line of scrimmage.

The Patriots have fallen in love with an unbalanced offensive line. Left tackle Matt Light is an eligible receiver seemingly every other play.

Light is having a rough game. Schobel shrugged him off to make a spectacular catch on the interception return. Light also gave up a 10-yard sack to Schobel and has been penalized for tripping.

Sensational hit by Leigh Bodden to prevent a first down. The Patriots cornerback jarred the ball from Lee Evans for what would have been a critical conversion late in the second quarter.
