There is a .001 percent chance of Miami trading from 5 to 3 to get a tackle. This is likely either Miami throwing more smoke or Detroit leaking this info so that other teams that are interested might trade up. I’m guessing the latter.
Detroit likely overplayed their hand and the third pick turns out isn’t nearly as valuable as they thought it was going to be. So now they’re trying to drum up some last minute trade interest. But when Detroit, Washington, Arizona, Carolina, and Cleveland have all been rumored to be interested in trading down in some capacity, teams are likely less interested in paying that premium on pick 3, when they can get OT2 or OT3 at 8 with Arizona’s pick.
Edit: trading from 18 to 3 is far more believable. Costly, however if they feel strongly that Wills or whatever tackle they have rated highest is worth potentially a second and next year’s first over someone like Austin Jackson or Josh Jones, I see that a plausible. 5 and 3 sounds more like something they would do vs 3 and 18.
