(Washington, DC)  --  The Seattle Seahawks have another memorable event for their Super Bowl scrapbook after being honored at the White House.  President Obama welcomed the NFL champs yesterday, but lamented the absence of Marshawn Lynch, saying he'd like to get a few pointers from the running back on how he handles the media.  The president praised the Seahawks' team spirit, the 12th Man, and the volume that emanates on NFL Sundays from CenturyLink Field.  Head coach Pete Carroll called yesterday "an extraordinary day" for the team.
