Very good player, but IMHO a minor quibble that a "star" means one is known by local sport fans generally and perhaps even by the fans of a sport league generally, while by contrast a "superstar" is somebody known nationally, if not internationally, by average folks who may not even follow any sports at all, e.g., Shaquille O'Neal, Patrick Mahomes, etc.
A good rule of thumb is whether somebody has been in an insurance commercial or appeared in network commercials for non-sports timeslots, If not, at best they are a mere star.
Of course, somebody could be a "superstar" to you subjectively, and there is nothing wrong with that if it makes you happier.
