According to NFL Draft Inside, and also confirmed by Lane Adkins from the OBR, the Dolphins have begun to preliminarily discuss a trade up with both the Browns and the Raiders. The Dolphins have a pair of 2nd and 3rd round picks this year and are undoubtedly looking for a LT to help protect Tannehill.

I know I'm not alone when I say that this is exactly what I want to happen. Falling back to the 12th pick would allow us to add more picks in a very deep defensive draft. This will help us address several key positions where we still need a starter and we really wouldn't see a tremendous drop off in talent between picks 6 and 12.

If this plays out, we can sit back and allow SEVERAL players to fall into our lap: Eifert, Hopkins, Austin, Mingo, Rhodes, Richardson, Cyrprien, or Warmack would all become legitimate names for the Browns to take at 12 and I would be happy with any of those names + another name in the 2nd round.

This report seems legit, so it will be interesting to learn the details ( if any are shared ) for what the Dolphins / Browns are asking. The Raiders asking price should presumably be higher than the Browns, given their stronger draft position but if the price is right, I strongly believe this is a move the new Browns' regime needs to make.

Below if the Draft Value Chart according to WalterFootball:

Essentially, as given as an example on the site link provided above, if a team wanted to trade up from 3 to 1, it would cost them 800 points, which would then have to be met by the picks provided in the trade. The Dolphins would have to give us 600 points, so their 2nd and probably a third or 4th. The Dolphins have picks 42 ( 480 points ), 54 ( 360 ), 77 ( 205 points ), 82 ( 180 points ) and 111 ( 72 points ).
