This is what I think the Dolphins should do.
1. Fire Gase and hire a new coach and staff
2. Trade Tannehill.
3. Move on from Landry, Suh, James, Kiko, Branch, Pouncey and any player who costs too much against the cap.
4. Draft a QB
5. If he struggles play his backup right away
6. If his backup struggles play the 3rd stringer right away.
7. Hire a new coach and staff.
8. Don't ever, ever pay anyone, keep the best cap situation in the league. Strictly build the team by good drafting and scouting as soon as anyone gets good and commands a big salary let them walk.
If this doesn't work the same plan will hold true for every season until it does. We will probably suck for a long time but at least this website will be happy.
