What Miami needs is somebody different selecting o-linemen (Draft and Free Agency) because their recent history in this area has been pitiful. They keep spending 1st round picks on o-linemen who turn out to be JAGs. (Tunsil included; no matter what you think of his play, he was still a liability due to his amount of penalties.) Also, what good has it done for Miami to have two or three 1st round picks on the o-line, yet still struggle to protect the QB and convert 3rd or 4th and short on the ground? Every year it's the same thing; Miami's o-line needs fixing. This suggests that even though coaching may have some effect, Miami keeps picking the WRONG linemen! Other teams can find perfectly capable linemen in the middle rounds or even later in the draft and put at least an average o-line on the field. Give the Fins 5 average o-linemen and it would be a HUGE improvement!
IMO, o-linemen should be old-school; nasty, tough, and physically dominating. Everything went downhill when Philbin wanted "finesse" wussies. Free Agent Incognito was Philbin's best lineman (Jake Long was injured and done for), but Philbin didn't want him so Richie went on to become a Pro Bowler as a Buffalo Bill. Gase's o-line probably allowed more tackles in the backfield than any other team in history. And I hate to say it, but this current o-line is probably the worst of them all when it comes to protecting the QB!
