Right now, in my opinion, some of the best QB play is coming from Deshaun Watson (1st round, 12th pick), Russell Wilson (6th round, 75th pick), Lamar Jackson (32nd pick), Patrick Mahomes (10th).
To rebuild a franchise and draft a QB to carry it you don't have to have a top ten pick. You need a pick, in general, a good scouting team and a lot of luck.
High first round QB's since 2000. Want any of these guys?

If Miami is smart they will be able to use all three picks in the first round to build on what they have now; Miami does have a decent talent base.
Side note - New England is only one game up in the AFC East. They could actually, feasibly, go in as a wild card (and Miami could help). I'm sorry but I will take a slightly lower draft position heading into the last game of the season if:
*New England wins they get the division and a first round bye
*New England loses and they go in as a wild card and go on the road
*Miami pulls up the ultimate spoiler and does the latter.
That would be a great way to end the season. AND...Miami still has a lot of picks.
