Someone mentioned this on another thread and it seems like a good idea in theory: why not move Williams to SB's position in 2010? Williams, like 2008 Brown, has decent speed but is completely lost at safety - bad in coverage, out of position, etc.
The problems I see are that we already have a lot of tweener types (more coming) and few true safeties.
Assuming we made this switch, what does our safety depth chart look like next year, including current and likely future recuits? Is it completely unworkable?
