You guys are looking in the wrong place.
The Raiders have selections 12 and 19. Not 11 and 13.
So a potential trade with LV would give MIA selections 12, 18, 19, **25 (wherever the HOU pick lands).
Not sure LV would offer that deal. By the point value system most teams use, its an overpay by a couple hundred points.
I’m not sure I’d go for that trade anyway. I might be more tempted for another 1st in 2021 than another this season. Say #5 for #12 their 3rd rounder this season (#80) (they don’t have a 2nd) and their 1st rounder in 2021. Something along those lines.
That‘d give MIA 12, 18, **25 this season + another 3rd this season and 3 1st round picks in 2021 too.
2020‘s first three rounds would be: 12, 18, **25, 39, 56, 70, 80
Pretty nice for a rebuilding team.
