A new shirt being produced by Old Navy states that the Houston Texans had won the 1961 AFC Championship.
One problem, though. The Texans first NFL season was in 2002. In fact the Texans finally made their postseason debut this past season.
The Houston OILERS, not the Texans, won the 1961 championship.
Old Navy has a new line called "NFL Team Champions Collection" and has already seen many problems. For one, the AFC didn't exist in 1961, it was the AFL. They have done the same thing to NFC teams too by calling them NFC champions, and not NFL champions.
Two shirts that they have produced, the 1969 Kansas City Chiefs and 1968 New York Jets, wrongfully states them has NFL champions even though they were part of the AFL. The merger between the AFL and NFL didn't happen until 1970.
