I said it in the other thread and I'll repeat it here. It's the Tournament of Champions, it's up to the PBA to decide which champions they invite. If they choose to invite HOF bowlers, if they choose to invite the winners of the RPI/RPC, if they want the seniors there, or winners from international tournaments, that's there prerogative. They've invited a lot of different groups in the past and they've changed the field for the TOC several times. Used to be just the past 64 champions. Now it includes all former TOC winners, even the guy who won in 1968. Used to include amateurs (Pat Healey, for example), now it includes the winner of the Women's World Series Championship.
