That was not a drop. Knox had the ball in his hands and the defender was able to knock the ball out of his hands. That was good defense.
A lot of people are making it sound like Knox has regressed back to his rookie year, which is false. Yes, all fans see are the big contract he signed and therefore he should be an All-World player.
I understand that argument, however Knox has been used a lot more as a blocking Tight End than as a receiver.
We have issues on offense, Knox is not one of them.
