We really did not finish in last place too often from the 70's through the 90's. I think 1992 might have been the only time.
It's funny, because I used to tell my fellow Sox fans, for decades, "I'll take 10 last place finishes for just one ring." Well, we may hit 10 last place finishes in my lifetime, but 4 rings is 4 times all I ever hoped for in all of my sports fandom.
We might even reach 10 last place finsihes from the 70's on, before we reach 10 rings, but to me, the 4 outweighs them all, and my guess is we reach 5 before I'm in the ground.
