Warmack and Mingo are the only players worth taking at 9 and 13
The only players I use the #9 and #13 picks on are Warmack and Mingo.
I don't think Milliner is worth a top 15 pick. He looks like another Kyle Wilson to me. Nassib won't fit in Mornhinweg's west coast offense, nor will Geno Smith. Cordarrelle Patterson won't fit on a roster that already has Holmes, Hill, Kerley, and hopefully Braylon Edwards. Austin is another Kerley, don't need him.
Otherwise, if Warmack and Mingo can't be had, Idzik should trade down into the mid 20s. The draft value chart says you can get a late 1st AND a 2nd for the 13th overall pick, so find a team picking late 1st looking to move up and trade down, scooping their 2nd rounder as well.
In the 2nd round, I think if Mike Glennon is there you gotta take a shot with him.
