Seahawks coach Pete Carroll insisted Wednesday the trade for veteran left tackle Duane Brown was not in reaction to the anemic running performance Sunday against Houston, when Seattle was held to a season-low 33 yards on 21 carries, 30 of which came on four attempts from quarterback Russell Wilson. He also insisted that performance, which tied the season-low of last season against Buffalo, was an outlier even if Seattle is just 21st in the NFL in rushing this week at 97.6 per game. “You guys want maybe to make this big statement about last week,” Carroll said. “Last week was a lousy game for us on the line of scrimmage and the running game. I don’t think that’s how things are going or how it is. I just think that’s how it happened.” Still, Carroll and the Seahawks have come to a conclusion as the season has neared its midway point and the running game remains one of the team’s biggest problems — that it’s time to give one running back the bulk of the carries and see what happens instead of trying to spread things out evenly among the team’s various tailbacks And for this week, the beneficiary of that decision is Eddie Lacy.
