In addition to hawking Tom Emanski's instructional videos, Fred McGriff was quite a good ballplayer.
Perhaps one of the most memorable trades in Braves history was when they traded Vince Moore, Donnie Elliott, and Melvin Nieves to San Diego for first baseman Fred McGriff in the summer of 1993.
McGriff already had 209 career home runs at the time of the trade, and those who watched the Braves at the time could tell you what exactly happened the day of his debut: on July 20, 1993, the press box at Atlanta-Fulton County Stadium caught fire, and he hit a game-tying two-run homer.
