Here's a look:
The biggest development involves rookie offensive lineman Jake Fisher being the backup left tackle and left guard. He didn't play guard during the preseason, though there was talk during the pre-draft process and even after the Bengals spent a second-round pick on him that Fisher could play guard as a rookie.
After all, Andrew Whitworth has the starting left tackle spots locked up, but both guards Kevin Zeitler and Clint Boling have missed extensive time due to injury during the past two seasons. Still, Fisher didn't play guard in the preseason, so this is apparently something they've been practicing when the media isn't around.
The same goes on the right side with veteran Eric Winston being listed as the backup right guard and tackle. He's spent his entire career at tackle, but apparently has gotten some work in at guard this offseason. It would be interesting to see exactly what happens if either Zeitler or Boling were hurt and who actually subbed in for them. Hopefully, we won't be finding out this season.
Brandon Tate is listed as the fourth receiver. That's disappointing... Hopefully, Rex Burkhead is ahead of him during actual games. Tate is also the starting kickoff returner. You weren't expecting to see something different, were you?
Margus Hunt is a second-string defensive end behind Carlos Dunlap, despite a strong push from Will Clarke this offseason to try and move past Hunt on the depth chart.
Ignore the safety designations. George Iloka and Reggie Nelson spent time at both free and strong safety last year, though Iloka was primarily played at FS while Nelson was at SS.
Chris Carter is listed as a third-string strongside linebacker, despite getting reps with the first-team defense this week.
Keep in mind, Marvin Lewis doesn't actually put any value into depth charts and has admitted to only releasing them because he's told to, so take everything you see here with a grain of salt.
