Yes of course you don't need big WR. For the offense we run a bigger WR would fit better though and bring more to the table then a small non-physical WR brings. With all small WR you should spread teams out. We don't do that. We do the opposite of that.
Exactly, that why I hope the Steelers consider Randy Fitz for OC, he knows how to run that offense and Ben will elevate his play and the receivers as well.
