Left tackle -- Max Starks vs. Mike Adams. Adams was the Steelers' second-round draft pick; we'll see if he's ready to unseat the veteran Starks at the left tackle position.
Cornerback -- Cortez Allen vs. Curtis Brown. Ike Taylor is slotted into one of the two cornerback positions, and Keenan Lewis will likely get the other, but even that's not guaranteed at this point. Allen and Brown are next in line for playing time, with Allen likely having the edge.
Backup running backs -- Isaac Redman vs. Jonathan Dwyer vs. Baron Batch vs. Chris Rainey. Redman will get most of the carries at the beginning of the year as Rashard Mendenhall recovers from injury, but how carries will be distributed after that is an open question.
