OK.

solo = 2, assist = 1, sack = 4, INT = 6

Do I start David Thornton or Keith Bulluck?

Until we see something to suggest a change from 2007, it's very hard to recommend Bulluck over Thornton. Neither is necessarily a better tackler or big play option at this point, so I'll stick with last year's trend and vote Thornton.

I would go with Bullock simply for the upside. While Bullock may revert back to last year, he does have much more upside than Thornton. Basically, if Thornton has a better game than Bullock, it would likely not be a big difference, while Bullock very well could have a much bigger game than Thornton. I don't think there is risk starting Bullock.
