Kiel's numbers have been on this downward slope the last few weeks (I know he was hurt this past week).Michael Lewis', Polamalu (prior to last night) numbers not great lately.I'm just wondering if these guys should be bumped down on the cheatsheets a bit. My feeling is that since it is so hard to predict a CB's performance, that you have to put the safeties at the top of the ranking by default?They don't seem to get TD's and occasionally get sacks.So is it better to take a chance on corners who get picked on, or safeties with more consistent tackle numbers?I have those three guys above and they have sorely dissapointed me...making me wonder if I should rethink my strategy for DB's.
