There was a play (probably more than one but thinking of one in particular that I saw and recall) where Lee took the snap and immediately looked left. Looking, looking, looking, never took his eye off that receiver not for one split second. And that is where the throw went, there was not a doubt that was where the ball was going. And it was incomplete, knocked away.
I know it has been talked about and complained about for years and years, not just Lee, but to telegraph that badly, and the other receivers, why bother running a crisp route when you know the play is not coming your way, not even a chance that it will come your way.
Don't know, coaching? Technique not being taught? Not practicing enough? Just too locked in too many times and not seeing other options. Hard to watch anymore, just hard to watch.
