Why is basketball so susceptible to corruption?

Did you know that the NCAA (National Collegiate Athletic Association) in the USA recently banned six basketball players for game manipulation and illegal information sharing? Not only that, but I also found that basketball is among the most susceptible sports to corruption compared to football (which I always thought was the most corrupted sport in the world)… What could be the cause of this?

That’s a news and strange to hear that, because I also thought that football was the most popular and corrupt, don’t know what would be the cause
