Needs----secondary help, ILB, NT.
1--if Earl Thomas FS is there this is a no brainer. However, he probably wont be there.
And since he wont be and the only other immediate impact player on the board at 18 is Mike Iupati (with the thought that the Steelers are actually satisfied with there O-line), then I personally would trade down.
Here is what I would try to draft.
1-Jared Odrick DT--scouts are calling him the best run stopper in this draft. Great motor, great physicals---if you like Aaron Smith then you will love Odrick and he is so much farther along at this stage than Smith was.
2-Daryl Washington ILB--personally I think when it all said and done he turns out to be the best ILB/MLB out of this draft.
2/3--Chad Jones FS---extra 2nd or 3rd from trading down---he is everything that Taylor Mays is not and yet has nearly the same physical set of skills. Not as fast but still plays with an above average football quickness and instincts.
3-Amari Spievey CB---perfect 3-4 zone blitz corner. Great size and physicality and he has shown solid/descent cover/ball skills.
4-Alterraun Verner CB---yep! back to back CB's. Say what you want about Verner but this kid has just spent the past few years at UCLA making big play after big play. I think one day he have a chance to be considered a mid-round steal.
5-Matt Tennant C---started every game for the past three years at B.C. Solid pass blocker who is decent at run blocker and is considered an above average puller. Getting stronger will help him but he has shown that he is no slouch.
