Bruno Boys and Draft Sharks led the way in year four of the Accuracy Challenge created by the Fantasy Football Librarian.

Announced by co-manager Donnie Campbell of TheMostCredible.com at the Fantasy Sports Trade Association awards dinner Tuesday night in Las Vegas — and via The New York Times‘ Fifth Down blog Wednesdsay — the Accuracy Challenge recognized Bruno Boys for delivering the most accurate set of preseason fantasy football rankings in 2010.

Draft Sharks, meanwhile, stood alone atop the ranks in football stat projections, edging 2009 winner RotoHog.

Not to be pushed aside, RotoHog managed to come out on top for the second straight year in baseball projections.
