There generally is one, although it would be hard to top last year's jettisoning of Rudi and Big Willie. I don't see anyone who leaps out as an obvious candidate, though, except maybe:
-I don't know how much of a "surprise" it would be, but I think with all the other safeties on the roster Marvin White picked a bad time to tweak his knee.
-This is kind of off the wall, but there is another long snapper in camp, and cutting Brad St. Louis to save a few bucks sounds like just the kind of bonehead move the Bengals have pulled in the past.
Any other obvious candidates?
