Why is the WNBA alarming at all (other than the fact that we shouldn't be throwing dildos on the court at all, of course)?

I'm just not sure why anyone would take a bet against someone who can single handedly make their side win. It would be like someone making a bet that I won't eat a hot dog for lunch tomorrow. Of course I'm going to eat a hot dog for lunch tomorrow. Why is there anything alarming about that? It's just stupid that anyone is taking the other side of that bet.
