Well, have you seen Kitna's post snap reads in Detroit this year?
Hard to make a proper read when your flat on your back before the recievers have run their routes, I just think this put it into Harrington that he has to rely on his pre-snap in order to get the ball off before getting sacked. And let's face it Miami's line has been a bit better but is still so sporadic that it would limit confidence in the time given to change up your read post snap. I think if he can get over the whole confidence issue with an O-Line that consistently gives him time that he would be less robotic and gain more poise in the pocket.
But the same has to apply to Culpepper, everyone criticized him for being to dumb to make reads etc.., early on in the year but as the season has progressed it becomes more and more obvious that the line just doesn't provide enough time to make reads downfield. I think Harrington was trying but when he did, either recievers weren't getting open or the Line was breaking down much the same as we saw with Culpepper.
I still contend that our biggest problem is a lack of a playmaker reciever.
Then O-Line we need to beef up the left side.
Then we start evaluating QB's.
For the last 5 or more years we've been swapping QB's without ever upgrading the line or the recieving crew and all QB's have failed. Eventually you have to start fixing the other problems to give these Qb's a fighting chance.
