Drafts are great when they're a) football-related, or b) actual, normal beer. Unfortunately, the latter isn't necessarily the case at the Seahawks' home stadium, CenturyLink Field. Seattle news station KOMO conducted a test of their draft beers and discovered that a whole slew of them (six in total) were diluted between 0.2-0.6%. Which might even be illegal.
KOMO took samples of Stella Artois (down 0.2%), Bud Light (down 0.3%), Redhook Brewery No Equal (down 0.4%), Shock Top (down 0.5%), Bass Pale Ale (down 0.6%), and Budweiser (down 0.4%) to a lab and determined that they all contained less ABV than advertised -- a discrepancy larger than 0.3% is technically against the law. These beers are already around $8-9 apiece.
Anheuser-Busch, which supplies five out of six of them, has commented that the circumstances and variables involved in the tests might've affected the results negatively, and has said (according to Deadspin editor Barry Petchesky) that it monitors all of its beers to make sure they're up to standards. So only time will tell if these drafts are fantasies.
