I was playing as the Chargers vs Raiders and I had just scored a touch down to get a lead late in the 4th, I supersimmed my PAT, the ensuing kickoff and the first play from the Raiders... The Raiders completed a pass but was tackled on the field so the time kept running, I went back into the game at the 2nd down mark and right away my offensive players got into defensive positions as the Raiders defensive players got into the offense spots.
The result? Matt Shaugnessy attempted to throw a pass against my offensive starters playing defense. Rivers and Gates playing some LB. It was pretty weird but after an incompletion, the positions were normal again.
