Right after Lamar Jackson won the Heisman Trophy, it fell into the hands of Johnny Manziel ... which can only mean one thing -- Lamar doesn't believe in jinxes.
Louisville's superstar QB was with Manziel in what appears to be a hotel room -- shortly after the ceremony, and Johnny Football couldn't keep his hands off the hardware.
Manziel posted the video and photos to congratulate LJ, but also seemed to be remembering his glory days 4 years ago when he was college football's best player.
Jackson's not going pro just yet, but considering how Manziel's NFL career has gone to this point .
