Saints beat writer Jeff Duncan on the RB situation: This is the marquee competition of camp. Rookie Mark Ingram and veteran Pierre Thomas have alternated reps with the first team throughout camp, and both have had their moments. Darren Sproles will man Reggie Bush's old role as the satellite back and steal a few carries to keep defenses honest, but Ingram or Thomas will be the primary ball carrier. The running back spot is similar to wide receiver in Payton's offense. Regardless of who starts, the final number of reps will likely be similar between the two.
If true, this would be a fairly big blow to Ingram's stock. Thomas has had trouble staying healthy, but when he's on the field, he's productive.
