Walt, your grade on the Earl Michell pickup by SF is off completely. Yes while he isn't a big threat in terms of DT look at all the defensive tackles, san francisco has? its mainly dial and purcell who have been doing the work and they need somebody else on that line. So this is easily a C+ or B- grade Free agent. While Mitchell did deal with injuries recently, SF is adding to the depth and at this point its a good pickup.
