Rice and Dukes should definitely be in, since Rice was winning titles in 1987, and was teaming with Dukes by 1988.
Sbraccia is an interesting case as he technically did debut in 1984, but was only 14 years old. He wrestled his first match at 16 in 1986, so I guess technically he would turn 18 at some point in 1988, but I don't really see him leaving New England until he finishes high school.
