Lazy hires.
It's been the buzz word of the offseason for the Steelers, despite the fact they haven't even made a hire this offseason.
But the assumption has been that in this twisted logic that if Mike Tomlin elevates someone from his staff to take a higher position, he hasn't done his homework.
Thing is, the homework was already done. For example, when you hire an offensive assistant, the idea is that perhaps he'll grow into being an offensive coordinator. The same thing goes for the defensive side of the ball.
That's especially true if they already have some experience coordinating, even if it's at the collegiate level.
