I don't actually think DJ is open here, at least not in time. He would be if he was the 1st read but he's not. Pickett looks left first. Watch it frame by frame. Pickett has to handle the shotgun snap first. He doesn't even have the ball with his feet set until 2 seconds on the film. By second 3, he starts looking to DJ as the second read.
Pause it at 3 seconds. Where is Pickett supposed to throw it to DJ? DJ is on a dead sprint and Pickett would have to lead him. But that would be throwing right into the DB covering the WR from the left (Austin?). So Kenny has to wait for the next window for DJ which is after the 2 WRs clear each other. That's at 4 seconds of the clip. Pause it there and Pickett is about to get hit.
This would have been an easy TD but the OL failed. Watch the OL frame by frame. Moore has Garrett and makes contact. Semoalu(sp?) and Cole are doubling the DT, but Cole is looking right. Semo feels Moore getting blown up so he comes off his block on the DT to help Moore assuming Cole has the DT. But Cole is still looking right and just lets the DT club him out of the way. Either Cole or Semo messed up the assignment. They get that block and it's an easy TD.
I also think the WRs messed up. They nearly run into each other. I don't think the slants are supposed to meet like that. One of the WRs were probably supposed to take a different angle to be more underneath the other.
