I've been banging this drum for awhile but if the top 7 prospects are gone by our pick (garrett, thomas, adams, fournette, howard, hooker, allen) .... a trade down makes a lot of sense.
Even if we overdraft McAffrey at pick 15ish, picking up an extra second will allow us to do the following
1- Mcaffrey RB
2 (1)- DE
2 (2)- SS
2 (3)- WR (route runner or speedster)
We immediately fill a ton of needs on our roster, you could also envision a scenario where we package two of those 2nds to trade back into the first.
