OTA's are in full swing, and there are a few starting positions up for grabs in NOLA. The departures of Tracy Porter and Robert Meachem have left the door open for quite the competition on those fronts. Also, if the Will Smith suspension holds up, the Saints will be having an open competition to find the starter opposite Cameron Jordan for the four games.
I'm not including the open wide receiver position left by Meachem for the simple reason that Drew Brees spreads it around so much that it doesn't matter who the starters are. I used the same logic with the running backs. There's no official starter in that group. It goes by matchups every week.
For a 13-3 team, the Saints will have a few more open starting spots than usual, but they also have the depth to prepare for it. If the players weren't on the roster, Mickey Loomis worked hard to stock up the cabinet either through free agency or the draft. With all of this talent in NOLA, it doesn't really matter who starts because the Saints will always "Finish Strong."
