I think with how often Chris Barnes makes shows, or has at least over the last few years he would have a legitimate chance. I know Barnes is roughly 10 years into his career on tour, but the beginning of WRW career was very similar, a lot more 2nd's than 1st's. If Barnes can just have a few tournaments where he wins that title match handedly it may very well get him started.
Then again the person that may catch WRW may not even be bowling on tour yet, maybe there's a young natural out there that is going to come up years from now. And just remember, noone really thought anyone will catch Earl.
