jimmy smith VS Cary Williams

can anyone figure out who is the safest bet to be on the field more often for the ravens?  in a 2 CB starting league, does it make sense to try to start 2 CB from the same team?  seems like it would garner a bigger total for good run defense teams that may be ahead in the score anyway.  any thoughts on this strategy?

I would be a bit weary of drafting two CBs from the same team. There are so many unknown CBs that emerge during the early part of the season that it makes little sense to put "all of your eggs in once basket." If I had to choose between the two, I would go with Jimmy Smith.
