I don't think the Steelers use their RBs very consistently or effectively as receivers. In the past, you could have chalked this up to FWP's stone-handed ways. But even Willie is a more reliable receiver now, while Mendenhall and Moore are both solid receivers. And Stefan Logan could be dynamite if used occasionally as a 2nd- or 3rd-down receiver out of the backfield. 

The Steelers need to find more creative ways to get the ball to their backs. We've seen a few successful dinks to Mendenhall, Moore and Parker this year, but overall the Steelers haven't been consistent. Often it seems that Ben only passes to the RBs when all else fails, instead of calling their numbers in the huddle.

That's maybe due to Parker's influence in not exactly being the best receiver. But it's way too easy for teams to simply crowd the line and stop the Steelers running game. And your WRs won't always be open.

I'd like to see the Steelers put in more RB screens, swing passes, etc. Other teams use these plays very effectively,  but the Steelers frequently look awkward when they try to execute them. Maybe this is due to a still-developing coordination by the OL--I don't know.

My beef with Arians has always been that he only has a few tricks up his sleeve. With the exception of Ben's uncanny escapability (something that nobody can coach), it's pretty easy to develop a defensive game plan when you play the Steelers. In most cases, they're gonna run short or throw long. Many of the really spectacular offensive plays this team makes are purely the work of #7.

Arians isn't finding ways to exploit the full range of offensive weapons available to him. That's why I think the team still has trouble scoring points at times.
