Well, we had to have the Cubs curse end first, it had to be that way, for Cub fansanity.
I do think the Indians are the only original 16 team that hasn't won since expansion started in 1961. (of the other 15, I believe the Pirates in 1979 is second longest, of course since the Rangers are the oldest expansion team to not win it-birth in 1961, they are 2nd longest. And Houston at 3rd longest-birth in 1962, have a chance to end theirs)
The Cavs won one, so no pity there.
Note: Other expansion team not to have won and came into existence before the Pirates win in 1979: Padres, Nationals/Expos, Brewers in 1969, Seattle Mariners in 1977
