The big name here, of course, is Smoltz. He was a freshly-minted Brave at this point, having been acquired late in the 1987 season. He made his debut July 23rd against the Mets and got a win. So though he would have a rocky 88, his debut actually was a preview of his excellent career.
Ron Gant was the bigger name in 1988, though, and he would have been a good choice for a player feature. He put up an impressive rookie season in 88, getting right to the cusp of a 20-20 season (19-19). His OBP was pretty good given his batting average, too.
The rest of these folks are pretty much non-entities. Jose Alvarez had been out of the majors since 82 at this point. Cesar Jimenez never made the majors; in fact, he was still in A ball at this point so his inclusion is baffling. Paul Runge was at the end of his career. Russ Nixon…well, Bobby Cox?
