That would be an interesting scenario. I would lean toward taking him, unless I could get a really good trade up offer.
I mean Miami could really wear teams down and that would protect against overuse by Ajayi as well.
I look at the draft a little different than a lot of people. If you constantly draft for needs and not BPA you end up with a roster that is missing elite talent. The Dolphins have been a slave to need for so long, although we saw that change a bit last year. Fournette is a great talent who has been compared to Petersen. What would be wrong with having amazing talent and depth at running back.
Obviously, the chances that this happen are slim. I think Miami could be looking at the same scenario with O.J. Howard, though.
