An examination of four hot issues from the Seattle Seahawks 20-13 win over the Tennessee Titans:

Defense corrects recent problems: Seattle's defense did not allow the Titans to reach the end zone. The only touchdown for Tennessee came of a 77-yard return by Jason McCourty of a botched field-goal attempt on the last play of the first half. The defense held Tennessee to two field goals, and the Titans rushed for only 66 yards on 20 carries. And the Seahawks' defense didn’t give up the big plays that have hurt them the past two games. “We cleaned up the things we needed to clean up," said cornerback Richard Sherman, who had one of two Seattle interceptions.

Pass blocking is improving: Quarterback Russell Wilson was sacked twice Sunday, but one was a running play for no gain. Max Unger returned at center and coach Pete Carroll was pleased overall. “Solid, he said. “A good job in pass protection. They gave Russell a ton of time. He ran when he needed to as opposed to when he had to. I thought it was the best pass protection in the last few weeks. I think Max had something to do with it, for sure.”

Browner take a seat: Cornerback Brandon Browner was having a hard time covering Tennessee receiver Kendall Wright in the first half, so the coaches took him out of the game and inserted Walter Thurmond, who started the first two games this season when Browner had a hamstring injury. “We just gave [Browner] a break,” Carroll said. “They were going after him. We have plenty of guys to play and I wanted to make sure we were fresh. I had a chance to talk to [Browner] about some of the stuff that was going on in the first half. I just told him we were going to go with the other guys for a little bit. Brandon is an excellent football player. He did a nice job in the second half.”

Help is coming on offense: Carroll emphasized some of the issues the offense is having likely will improve soon with players who will get back on the field, including tight end Zach Miller and receiver Percy Harvin. “We have some guys that are going to juice us up in a couple of weeks,” Carroll said. “Zach will be back next week for sure. Percy is coming around the corner.” Miller missed the past two games with a hamstring injury. Harvin has yet to play a game in a Seahawks uniform after undergoing hip surgery Aug. 1.
