Let’s take a look.
#3 overall = 2,200 points
#5 overall = 1,700 points
The Dolphins have:
#39 overall (510 points)
#56 overall (340 points)
#70 overall (240 points)
For the Lions to get fair value they should ask for #5 and #39 (2,210 points).
Having said that, if the rumors are that the return is on the low end of the scale, it might be for #56 overall.
Why I hate it if they don’t get at least #39 overall - You’ve got to at least get fair value for the pick, even if it’s all gravy. Not getting at least fair value would be really weak on Quinn’s behalf.
Why I like it if they just get #39 overall - The Lions would likely be landing the same player they would have taken at #3 overall, so if you can do that + get anything else, that’s gravy.
Having said all of this, I’d still rather see the Lions take Tua at #3 or even trade up for Young.
