Yeah, HOF'ers only.
I did think it was a little strange, though, that at Eddie Murray's statue ceremony, just about every speaker made a point of emphasizing how Eddie was the best firstbaseman in franchise history, while Boog Powell sat 10 feet away. I mean, sure, Eddie was the best, but you know Boog had to be thinking, "wait, my teams won two World Series, I was the league MVP, I was beloved and they ran him out of town, etc."
