The only ones banking on 2020 only are fans. An NFL team does not have the freedom of just skipping a year. If they get Bridgewater it is a win-win for the Dolphins.
Bridgewater is young and nobody knows what his ceiling or his potential is. He played one full season. It was a decent, not spectacular, season. He had a bad injury and the Vikings simply gave up on him before he was healthy.
If we get him at a decent price range we have a potential starter for at least the next two years at our hands and maybe more. That does not eliminate to draft a QB in 2019, 2020 or 2021. It eliminates the pressure and puts us in a situation where we can look at the situation with no hurry.
The only people who will be upset are those who put all their eggs in the basket "tanking" because they have simply no idea how the NFL works. Picking up Bridgewater would be like going from "all your eggs in one basket" to "eggs in your face".
