It is well known that Bruce Arians and the Pittsburgh Steelers like to utilize 3 and 4 wide receiver sets to create mismatches with the defense. To be successful doing so, the WR units will need to be deep with talent. The starters are Hines Ward and Santonio Holmes behind them though; the 3-5 spots are unsettled as of now. Leading one to speculate concern, being the reason they have so many currently on the roster? Typically, you would expect 5 WR’s to make the 53-man roster, but this year 6 may not be of the question.
