While I think the jersey size is a small clue, I think there are many other more obvious problems...

Cant imagine a 94 gamer without the anniversary patch especially if it was given to him after a game??? (no chance of it being removed after the season, etc)

Perhaps some other members can confirm but I thought the majority of
the year tags were on the bottom tail of the jersey...don't recall many
Wilson tags in the collar during that era...

There are always exceptions, especially with higher profile players as their jerseys are the ones that 'disappear' more often than the others....so perhaps ask for more pics (the tail for one) and check out some other
examples of 94 jerseys....

This, along with some of the great feedback some of our members give, should give you a pretty good idea toward what to do..

trust my two cents helped somewhat...
