My final mock:
PIT
20.
Amarius MimsOT Georgia - like last year, we showed our hand early and Broderick Jones fell in our laps.  I like the same scenario happening tonight. 
51.
T.J. TampaCB Iowa State - I fully expect us to made a trade w/ this pick; but, if we stand pat  Tampa is a very good DB, who played along side Cooper DeJean.
84.
Zach FrazierOC West Virginia - I wish I could sit with Ark, Supe and Orge when this pick comes in but we'll save that for next year's draft.  There will be much rejoicing w/ this selection.
98.
Xavier LegetteWR South Carolina - Am I the only one who thinks trading for Aiyuk is crazy???  If it were me, and I know, I'm just a fan, I'd pick Legette here, who, has Deebo Samuels-like skills.  Just do it.
119.
Braden FiskeDT Florida State - Another A+ pick here.  Fiske will pair nicely with our existing DL youngster...
178.
Cam HartCB Notre Dame - depth and hopefully a future slot DB.
195.
Jared WileyTE TCU - I'm hearing/reading Muth could be traded during the draft.  If he is - that's a new hole that needs to be filled in.
