The officials clearly were emphasizing some of the new rules. But the changes most associated with the Seahawks -- defensive holding and contact after five yards on receivers -- weren't much of a factor for the Seattle defense.
The Seahawks were called for pass interference only once. Denver, however, was flagged for defensive holding three times, illegal contact once and interference once.
It wasn't the cleanest of games, to say the least, but not all that unusual for a preseason opener.
"I think it was just pretty sloppy play," Seahawks coach Pete Carroll said.
Carroll was more concerned about personal foul penalties after Denver touchdowns, one on linebacker K.J. Wright and one on cornerback Tharold Simon, who was ejected from the game for throwing a punch.
"It's bad football," Carroll said. "Giving people 15 yards on a kickoff, which is crazy. It's just poor decisions and a little bit of frustration. We just have to get stuff cleaned up and get their minds in the right place to make sure we don't do things like that."
