There are reasons Ryan Tannehill has clung to the Miami Dolphins starting quarterback job for seven seasons -- so far outliving five offensive coordinators, three general managers, and two head coaches, one of which happens to be a quarterback guru.
All those years, you see, Tannehill has been good at times and not good at others.
He’s been good enough to convince the Dolphins to let him continue. But he hasn’t been good enough to satisfy everyone he should remain indefinitely.
Even the current Dolphins brain trust, boldly supportive of Tannehill for three years, has private questions about him now.
