I don't know if this was already mentioned, but it looks like Fanatics makes Nike's gear for other leagues. I wonder what the perceived quality is of those "Nike" uniforms:
"For example, Nike is the official outfitter of Major League Baseball, but Fanatics has made MLB's Nike-branded uniforms for all 30 teams since 2017, when it acquired Majestic. In total, Fanatics makes close to 100,000 MLB uniforms each season. Fanatics also makes authentic NFL jerseys that carry a Nike logo, which are sold online and in stores."
