Basically, the article states that Head Coach Mike Tomlin (HCMT) and the Steelers are willing to "exhaust all realistic possible scenarios" in which to trade up in order to draft Florida guard / center Mike Pouncey.
This willingness to trade up is contingent on Pouncey's draft status slipping past 15th overall. At this point, the scenario could unfold for the Steelers to move up.
I'm not sure how I feel about this, but the Steelers are historically good at moving up in the draft to get the player they want without giving up too much. We will see what this brings Thursday, and I'm looking forward to it.
