I don't remember the exact situations. I agree with you regarding liking stats and exacts, unfortunately I don't have them regarding Robey. But, it was late in the year. It was not often. It was 1-3 times a game when he played a lot of downs and the oppositions knew he was going to play a lot of downs when we had 3 CBs in the game due to lack of depth usually when a man was in motion to gain the mismatch.
I don't dislike Robey at all. I like him....but, just for certain situations. Size is not everything, but, when you are 5 to 9 inches shorter than the WR you are one on one with it is very tough for Robey to win the battles.
Blitzing and covering the WR in the slot he is excellent. It is when he is covering the slot WR and they run motion or audible Robey and the Bills are at a disadvantage.
Once again, sorry for not having facts and examples...I would prefer if I did too.
I don't recall him ever losing his man either.
