I just realized the holograms on the back are different. What's odd is the hologram on this one is football-shaped, not flag-shaped as expected, and the one in the football set is round, not football-shaped as expected. We also don't have anything under 1996 Upper Deck Baseball or 1996-97 Collector's Choice Basketball, two other places these cards may have appeared, and who knows what hologram shape those have!
For now I've created an insert set under Road to the Cup and submitted an IR to move the standalone into there, then I'll add the other four options.
This ebay auction shows 4 of the 5 with a bunch of racing cards, but no backs are pictured to confirm hologram shape.
