Curses in normal everyday life are regarded as fact by just a small faction of the population. In contrast, curses in sports are mostly viewed as absolute truths with everlasting consequences.
One team regarded as massively cursed is our own New Orleans Pelicans. This curse is not due to a goat, or a poor fan interaction but simply a bug. The injury bug.
The Pelicans feathers have been infested with them for years and the 2018 season appears no different as Solomon Hill, Frank Jackson, and now Rajon Rondo have all went down.
Rondo suffered his injury during the second preseason game and it was mostly regarded as a small issue.
