Perhaps, in the case of "more players"; no, in the case of "more top players".
Tournaments aren't run in a vacuum. They're affected by other tournaments. So if we want people to come to our tournament, we have to offer something equal to, or better than, other local and regional tournaments.
This might be added cash, even if we're reluctant. If everyone else is enticing players with added cash, we might feel we need to match that, or do without players at our tournament.
Or it might be lower fees, or a better course, or some other enhancements.
