If I read the pros comments correctly, the PBA is paying ESPN to televise the matches, though. Perhaps putting it up for bid would get some money flowing in.
In the order of problems the PBA faces for viewership, I would rank them this way, greatest impact to least:
1) Going up against the NFL,
2) Being on Sundays in general during the time a lot of people in your core audience are in church,
3) No promotion on the network except when the telecast is on,
4) No wrap-up on SportsCenter unless Machuga does the flop,
5) Insufficient prize funds, thereby telling your viewers that this thing, in essence, really isn't a big deal,
6) Insufficient promotion inside bowling centers aimed at league bowlers,
7) Issues with the field (because of the low money involved, the guaranteed check to the guys that are there every week is a big deal ... thus, why I don't consider this a big issue for bowling versus golf)
