From what I'm hearing teams only have 12-14 first rd guys on their boards, so there may not be a very good trade back offer. If you're options only get a late 3rd or 4th, would you even do it? Don't thinks so.
I think either Chaisson, Kinlaw or McKinney, (maybe Delpit) should be the pick. But they may feel like one of the CB's (Terrell, Fulton, Henderson, Diggs, Gladney) offer more value or more of a need.
Any LB other than Simmons should be off the board. They just wouldn't give us enough value and need at 17.
My "Big Board" of players I'd want to take at 17 goes like this:
Young
Brown
Simmons
Okudah
Kinlaw
Chaisson
McKInney
Eepnesa
Delpit
Henderson
Fulton
Diggs
I know I ignored all those WR's and OT's, but IMHO it's just too deep a class to take one this early with so many top defensive needs.
