The Pittsburgh Steelers are halfway through the preseason, and just about done with training camp, yet there still remain a number of significant questions on their roster, at least in terms of the pecking order. Who will be their punter? Their nickel defender? How many linebackers will they keep?
And who will be in the backfield along with Najee Harris? The rookie first-round pick seems to be the only firm, 100 percent lock, though Anthony McFarland is a rather safe bet. It remains to be seen if they will keep three or four halfbacks; yet, like last year, they seem to see enough to like back there to want to keep four.
