Other than the hem, the other curious thing is the autograph notation. Mac didn't sign "70" until after the season... so that likely rules out an in-season swap of jerseys with Tony, when Mac would have added the "STL 25" notation. I can't say with certainty -- who can? -- but I have to believe the odds are greater that this is one of the extras Mark had made to give away vs. an actual '98 gamer.
