In the NCAA, they would have wiped taken the TD off the board. At least Tate realised he was wrong. If nothing else, it put his team-mates on special teams in a right mess, which in turn, made the defense start further back than they really had to after the touchdown, which is very silly and the reason why the Seahawks were annoyed. If nothing else, it really reflects badly on the organisation and Tate.
Rice is injured for the season, so for seattle, it's almost like Harvin or bust. They cannot rely on Lynch to bail that offense out, every single week, as good as 'beast mode' is. To allow 7 sacks on Russell Wilson is crazy. That O-Line needs fixing, fast, and should be a huge concern for seattle. But credit to seattle, they got the W. It'll go down in the books as a seattle win, they improve their record and live to fight another day. The top teams make big plays at key times: Seattle are a top team.
