ConvenientTruth, this is one of the most interesting posts I have seen in a while. Smartfootball is a great site, I have checked it out before.
Anyway, what do we expect? I think we will in fact see much more outside zone read in particular, from the recent pictures I have seen of Tannehill. He looks to be about 10 pounds heavier at the minimum, and much more muscular. Clearly he was given a weight program and he has the work ethic to come in exactly as they wanted him IMO. it could just be for added durability, but to me, his new body tells me he will be running more. Plus, the best thing he ever did in the passing game in college was rolling out and passing to the sidelines, away from traffic. The thing he struggles with the most IMO is throwing in traffic where he has to anticipate a receiver coming open. He can throw that little 6 yard slant to Wallace because his arm allows him to react and not anticipate at that distance. But intermediate throws are a problem for Tannehill when he needs to anticipate a cut. Seems to hesitate. So...more zone read allows him to be on the move and the threat of running is there either from him or the back, but then he can throw it too while rolling out. That extra threat of running means you can't just gang up on the receiver you think he will toss down the sideline to IMO. Still a pass first idea, but he remains a threat to run and that occupies a defender for a couple of seconds and has maybe another defender or 2 sort of leaning in anticipation of the run. Just makes it easier to throw. Also allows for screens in the passing game which will help him. He will still have to throw to the middle and do some intermediate distances on those horizontal routes he has trouble with, because you cannot avoid the middle completely. But this offense should play to his strengths more, and allow him to minimize the areas where he struggles.
This all comes with one huge caveat. Can our offensive line zone block? Like are they mobile enough? I also wonder about 2 details for Miller. One is when he has to read and react (when the hole does not open as anticipated and he has to find the open spot). He is fast, shifty and can jump cut as well as anyone in the business. But when he has to read and find an unexpected hole, can he do that? If the line can get zone blocking down, Lamar Miller has a chance to be very very good IMO. He will be better suited than even Moreno. Of course he also has to learn to pass block to get on the field as much as we would like, which is the other concern for me.
Those are some of my thoughts on this part of the offense this year. BTW I see you guys discussing how much Tannehill will run. I bet it will be less than RG3 his rookie year for sure. I think the entire NFL learned from that one. But it is something we can do and the fact that Tanny looks so much tougher now in the pics I saw tells me something is definitely up. May even be for more roll out passes where he may take off and run at times when it's there, followed hopefully by a slide!
Sorry if I rambled.
