Cena was notorious for wearing the host city's jersey the night of Raw to the ring. In fact, during his Doctor of Thugonomics gimmick, all he wore were pro team's uniforms as his pre-ring gear. It was a subtle, but effective way to get the crowd on their side. World Wrestling Entertainment isn't a stranger to free marketing for another business. If Cena is seen worn wearing a Kevin Garnett jersey in Brooklyn, kids will ask their mothers to buy them a Garnett jersey that night or the next morning. It's not a constant factor, but it still works. The West Newbury, Mass-native did many things for WWE in his career that is still ongoing. Utilizing cheap pops with his wardrobe was something he did for years.
