OJ Simpson -- #32 back in the day -- just posted a 32-second video he shot in L.A. ... and as far we know, he hasn't been back in years, and there's a lot of history.
O.J. was in a suite at SoFi Stadium Thursday afternoon, getting ready to watch the Buffalo Bills square off against the L.A. Rams.
Simpson was giddy with excitement, telling his followers, "Hey twitterworld, it's me, yours truly!!!" He made it clear, he's rooting for his old team, and seemed amped up for the game.
