Yup, surnames. There's no mention of suffixes — such as "III," "Jr." and "Sr." — because they are not really part of players' surnames. To the contrary, such suffixes relate specifically to players' first names. Robert Griffin III is Robert III, not Griffin III, in as much as his grandfather and father were named Robert Griffin and Robert Griffin, Jr. respectively. The "III" suffix is a strong and wonderful family tribute, to be sure, but should it be represented on Mr. Griffin's jersey? The same may apply to Steve Smith and that newly added "Sr." suffix. The lad and the dad are Stevonne Jr. and Stevonne Sr., respectively, and both are, of course, Smiths. However, there simply is no Smith Sr. Should the NFL have denied Mr. Smith's request, which was made even before his son was born? It's hardly the league's chief concern, but yeah, under its express surname rule, the NFL probably should have.
