I dont really agree with it either but Sherman should know his real potential. But its not like Tannehill is just some crappy QB prospect, he definitely can be as good as Matt Ryan I believe and for what its worth Charles Casserly on NFL network said he's better than all the QB's prospects in last years draft (minus Cam Newton) and that he compares him to Joe Flacco and Josh Freeman type prospect and if they all three were in the same draft together, he would choose Tannehill over Flacco and Freeman.
