Seahawks must improve on the O-line

INDIANAPOLIS -- The Seattle Seahawks must show improvement on their weakest link -- the offensive line -- if they hope to win Sunday against the Indianapolis Colts at Lucas Oil Stadium.

Quarterback Russell Wilson was under duress last week, to say the least. With three starters out on the offensive line for the game at Houston, Wilson was hit or sacked while throwing the ball on 16 of 34 drop-backs, or 47 percent of the time.

That was up 10 percent from the previous three games when Wilson was pressured on 27 of 73 drop backs (37 percent).

The Seahawks allowed 33 sacks last season, just over two per game. They’ve already given up 13 sacks this season, which is 3.25 per game.

Improving on that mark Sunday won’t be easy going against Colts linebacker Robert Mathis, who leads the NFL this season with 7½ sacks.

Seattle may enter the Colts game without four starts up front on offense, including tight end Zach Miller. He’s listed as questionable with a hamstring injury. Starting center Max Unger, who did not play last week, also is questionable with a triceps injury. Starting tackles Russell Okung and Breno Giacomini both are out.

One way to help the situation is to establish the running game with Marshawn Lynch. He rushed for 98 yards against Houston, but 43 of those yards came on one play in the first half.

Lynch averaged 5.0 yards per carry last season when he rushed for 1,590 yards. He is averaging only 3.9 yards per carry in the first four games this season.

The Seahawks have found a way to win and stay unbeaten despite their woes on the offensive front, but it will bite them at some point if things don’t improve.
