Do you people get your views on the legal system from TV or something? Have you tried a case? I haven't in 20 years, but I'm still involved in disputes. There is no sure thing. In 99% of cases there is a risk of losing for both sides. Plus it's expensive. Settlements are the norm as a result. UConn believes it's odds of winning are more than than zero. That's all that matters.
Here's the 1%. My friend handles Med Mal cases. A guy claims malpractice. The evidence...he had a procedure done and they essentially re-attached his penis and testicles upside down. Pictures were provided. The response: "how much do you want?". The defense is not winning that case. But even then it settled, because the damage amount could vary widely.
