Sanchez is still a good DB. Every player at every position has a bad game or two and playing the corner is not an easy thing to do (little or no support). I'm sure that his mother's battle with cancer is also having some effect on his ability/concentration. But regardless of how good your DBs are, they will inevitably be beaten by a smart quarterback who has suffient time to pass as well as time for receivers to run their routes. We need more pressure up front and better, more consistent performance from Karikari at safety (he has been the biggest disappointment back there)
Bringing Durden back wouldn't be a bad idea - it might help relieve some of the pressure off of Kent and Cox while they still learn the game. They have great potential but just aren't there yet.
As for 'hwgill' and 'sportsmen' out in B.C., feel free to tell Wally that Montreal will happily take Miles back. I'll personally send out a case of Montreal style bagels and smoke meat if that is of any incentive!
