OPI if anything, and I think since there was such little separation gained, it would be impossible for the deep wing to notice as he would be somewhat straight-lined if he was in proper position and still 10 yards ahead of the players. The B would have the best angle to see if he felt there was enough separation to warrant an OPI foul.
There was no contact for DPI, and in we know there MUST be contact even if he is not playing the ball at all.
