I hear you but his play has been helping them win games. If somehow they get to the playoffs he will have played a big role in the turnaround. Their pass defense is immensely better statistically than Pre Minkah.It's a combo of both. But I saw Andre Goodman go on a hot streak causing turnovers for us in 2008, get a nice contract from Denver and fall off a cliff. I saw Deltha O'Neal have 9 ints one year for Denve5, be so bad the next year they switched him to WR, and then get traded to Cincy and have 10 INTs. I dont think he would ever be considered a shut down cb.
Bottom line Minkah wanted to go. Here he was going to be asked to be a top guy, and in Pittsburgh he is arguably the 5th or 6th most important player on the defense. He is allowed to react more than be asked to create. Let's see if his play was a hot streak or luck
