The 18-200vr looks good, however I have not used it and have no opinion or exp with it. The 80-200 2.8 was one of the most common pro sports lenses before vr became available.
The 2.8 F stop allows you to shoot without flash at concerts, plays, auditorium shows, weddings, glamour, models, etc.
I will send you the info on the lens.
