Despite making key additions in free agency and the draft, the Pittsburgh Steelers still had a long list of questions that needed answered entering training camp. One of the biggest is their depth at corner. Joey Porter Jr. will be the team’s No. 1 cornerback and Donte Jackson seems to have the No. 2 spot locked down. Beyond that, nothing is certain. There are multiple dogs fighting over a limited number of bones, as Mike Tomlin would say. Defensive coordinator Teryl Austin seems to agree that the team still needs to see those guys fight it out a little more before making any decisions.
