The "Bagger here, bagger there, everywhere a bagger" mentality comes from our history. The PDGA didn't start allowing AM's to join to develop an Amateur base of players. They added AM's as a "future pros" division. It was all put in place to feed donors into the Open field. As soon as somebody played one good round, the Open guys would pat them on the back and say "time to move up." It wasn't time to move up and compete, it was time to move up and donate your entry fee to the Open division. If you didn't move up, you were a bagger. It was all a way to get more money for the Open guys to play for.
It didn't work out that way. There were a bunch of guys like me that knew that no way in Hell were we ever going to cash in Open so what was the point. We didn't move up to donate. The AM division swelled and the Open divisions stayed small. The Open guys kept yelling "bagger," but it didn't work.
The PDGA has tweaked things here and there trying to nudge people into the Open division. Allowing you to play down if your rating drops gives you a safety net. Raising the minimum rating on INT allowed a bunch of players that were donating in ADV to drop down, cutting the bottom half out of those huge ADV fields with the huge payouts from the mid 00's. All that was done to try to make those 970ish guys take a shot at Open.
It's not really working.
Disc golf payouts to AM's are so screwed up that it's hard to describe. People get so much stuff playing AM that there is no incentive to move up unless you are really driven by competition. A lot of us are not driven by competition. Disc golf is something we do for fun. If you are playing for fun, there is no way to make playing Open attractive when you can play AM, get a huge players pack and then win a bunch of discs. The only price you have to pay is listening to people call you a bagger, and that has never worked.
So we can look at a guys rating a call him a bagger. So what? Who cares? He doesn't. No one really ever has.
