Honestly the biggest problem I saw was what you talked about with his mobility in the pocket. He needs to be lighter on his toes, I would just like to see him be able to breathe back there a little easier, be more athletic. I talked about that a lot mid-season, that this is a kid that is only what like 25 years old or something? And he moves like Peyton Manning and Tom Brady do now, in their 30's. He's young and he's no Peyton or Tom when it comes to ball placement, reading defenses and checking into play calls, and so what he needs to do is use his youth to his advantage. I read that he's dropping weight. From what little I've seen of him in mini camps, his drops look quick, he looks as quick with his body in the pocket as Tyler Thigpen and at times I swear he looked even a little quicker. He doesn't have Thigpen's straight line speed, never will, but I was encouraged.
His problems aside from that, which I view to be the lowest hanging fruit, are pretty well publicized by now. There's no secret in it, not that I'm seeing. He really did rifle his checkdowns at times when he needed to show a lot more touch. If I remember correctly his ball placement tends to be high and right throwing to his right, low and left throwing to his left. I don't really have a problem with his long trajectory. There's just an awareness issue that he needs to clean up, that you hope will come with experience. Read the safety. Look him off once in a while. Know where you have trailing coverage that could come into your passing lane.
It will be interesting to see what he does this year with Brandon Marshall in the fold. I happen to think that the Miami WRs are going to go from a big weakness to a big strength. They'll rotate the three guys opposite Marshall. But if Henne doesn't fix his feet then it won't matter because Henning won't be able to protect him if the offense is trying to rely on 3-WR formations more often than 2-TE formations. Henning has been using his 2-TE formations as a staple in order to protect the QB.
