Playing Fantasy Football does not qualify you to be the in the front office or on the coaching staff of the Pittsburgh Steelers. They are professionals and you are not!
With Unger on board, they probably would have bypassed Urbik. Perhaps they select Roy Miller (went a few slots after Urbik) or another defensive lineman in the 4th.
The next year, with Unger on board, maybe they keep him on board and still take Pouncey. Or maybe they take Demaryious Thomas, Sean Weatherspoon, Dez Bryant or one of many other options.
Would be interesting to see how it would all play out otherwise with one pick changed...
