Gloves are harder than hell to photomatch honestly, and the only way I know my gloves that I get are from x game are because I get handed them personally. I take pics throughout the game and am able to photomatch (or I guess stylematch to anyone else) the gloves to that game and I put them with a ticket from the game into a ziploc bag and mark the player's name, position, jersey # and date.

FWIW for the most part NFL players don't seem to write their numbers on gloves (I've gotten several hundred over the years and maybe 2 or 3 have, MAYBE). I know college players do because the little white box area on the bottom of the palm closer to the wrist is perfect for that.
