Deshaun Watson is about to become the eighth rookie quarterback to start in Seattle during the Pete Carroll era. The Seahawks have seven years of evidence indicating why the Houston Texans and their first-round draft choice should beware on Sunday. CenturyLink Field is no place for kids. Seven rookie QBs have come into Seattle to start against the Seahawks since 2010. Only one has been victorious: Andy Dalton, in 2011 with the Cincinnati Bengals. The Seahawks’ defense with Carroll’s attacking pass coverage, fast, versatile linebackers, attacking edge rushers and brick-wall inside linemen have been about as daunting as Seattle’s roaring fans to spooked rookie passers. That’s been from Jimmy Clausen for Carolina in 2010 through Sam Bradford in 2011, Derek Carr and, last year, Carson Wentz and Jared Goff. The seven previous newbies have combined to complete just 56.7 percent of their throws with eight touchdowns, eight interceptions and a meager passer rating of 68.0. Those rookies have gone 1-6 in Seattle. Only two of those six losses have been within six points. The Seahawks have sacked those new guys 17 times in the seven games.
