What’s the argument regarding Settlement vs. a Trial?

According to Lowell “The Hammer” Stanley, in Norfolk, Virginia Beach, Portsmouth, Suffolk, Chesapeake, Hampton, and Newport News, Virginia, “Most Virginia personal injury cases settle before trial and there are many settlement considerations like strength of liability, risk of contributory negligence defense, future medical needs, insurance policy limits and jury risk. If settlement does fail, the case proceeds to Filing a Complaint that often includes discovery, depositions, expert testimony and jury trial”
