If you watched him in college, there was never any doubt that he could
make all the throws, sometimes even in actual game conditions.
I still want to know what it means to say he "knows 70-90% of the play
book". I'm going to go out on a limb here and assert that the Dolphins
will not be running the spread offense Texas A&M used. Tannehill wont be
running a zone read every third play. Does it mean that the terminology
is the same as Sherman used at Texas A&M? That's no small thing, but it
shouldn't be a big deal for a veteran QB to pick up either.
