Football Outsiders has out their list of “The Top 10 unfilled roster holes,” and the 49’ers make the list with their unsettled QB spot. Here’s the story:

1. San Francisco 49ers: Quarterback

The last time San Francisco had a quarterback accrue positive DYAR with more than 100 passes thrown is 2003; since then, they’ve had the worst quarterback in the league by DYAR in 2005 (Alex Smith), 2007 (Trent Dilfer, with Smith in second-to-last) and 2008 (J.T. O’Sullivan). While Shaun Hill was better than O’Sullivan, his DVOA was 28th in the league, at minus-2.8 percent. San Francisco struck out on Kurt Warner and added only aging Damon Huard (-54.7% DVOA last year) and developmental prospect Nate Davis this offseason, leaving Hill as the starter by default.
