Well, I disagree with you there, and so may a lot of other people. And the division of opinions is the problem. You wactch Henne, and see him go through his options on every throwing play - he regularly chooses the short dink and shys away from the vertical game.
If Henning was Marino's coordinator, do you think that Marksx2 would have not been productive?
Henne has choices, and yes, the coordinator does factor in......but, remember this, Henne is an NFL starting QB who can change a play at the line of scrimmage and go vertical. I question whether Henne has the swagger - confidence - leadership to do this.
My main point is that Henne should have been left in, for the season, so...in December....you and I would not have to have this debate. The answer would have been clear for all to see.
