I can't answer this in a vacuum without knowing what Miami will be doing. If we bring in the likes of Chris Foerster or Kippy Brown, then Tannehill, like any qb, would be hampered.
Personally, I'd like to see a system with more of a running game and that spreads the field more, while identifying matchup advantages pre-snap, like Peyton Manning does, instead of a progression system.
One very overrated issue has been the compatibility of Sherman with Philbin. We've heard that Philbin wanted McAdoo all along. While Philbie has known Sherman since high school, McAdoo and Philbin both came out of the Mike McCarthy Green Bay system. Mike Sherman preceded Mike McCarthy in GB and runs a different strain of the offense. Philbin and McAdoo may run something slightly different than Sherman ran.
