We've largely seen Mike Tomlin stick pretty much with what he knows or, should I say, who he knows when it comes to coaching hires.
His initial staff with the Steelers included a number of hires - outside of the people he kept - who were people with whom he had coached at previous stops.
But last year's hiring of Todd Haley as offensive coordinator was a step outside of that box. So, too, was Tomlin's hiring of Jack Bicknell Jr., as his new offensive line coach.
Looking at Bicknell's resume, it doesn't appear to have any direct ties to Tomlin or anyone else on his staff.
In fact, Bicknell, who has just four years of coaching experience at the NFL level, is something of fresh blood at this level.
The two stops he has made in the NFL - with the Giants from 2009-11 and Kansas City last season - have proven fruitful in different ways.
In New York, Bicknell helped coach a line that paved the way for a Super Bowl champion. In Kansas City, he coached a line that led one of the NFL's top rushing attacks despite the fact the Chiefs' QB situation was a mess.
With the Steelers, Bicknell inherits a line that includes promising young players Maurkice Pouncey, Mike Adams, David DeCastro, Kelin Beachum and Marcus Gilbert. All but Beachum, a seventh-round draft pick last year, were premium draft picks.
The onus will be on Bicknell to help those young players reach their full potential.
