Irish,
You touch a good point, but I don't fully agree with you. I don't think that a national league is the way to go per se, and it's not the coverage in the media that's going to save paintball.
However, promotion is a big part of what is needed, but this does not have to be promotion via TV. As has been pointed out, there needs to be a better link between rental days to walk ons to tournament ball.This has to start at ground level, which means that the site owners have to start TELLING people that there is more than just rental days. Invite players to come back for a walk on day, and you will see a snowball effect.
But what is needed is an "I can be the best" attitude. There are too many players that call themselves athletes, but do not deserve the title. In the UK there are a number of pro teams, for example Nexus, Tigers and Shockwave. Every serious player should aspire to be on one of those teams.
Spots on those teams are obviously limited, but of you show yourself to be the best damn player in the country, there won't be a team manager that's gonna decline you. In order to get to that level, you need to put in many hours of practice. I'm not talking three times a month, or once a week, I'm talking several times a week.
Every player knows which teams are the big dogs and every player would love to be on those teams. After all, it is the proverbial sh!t if you get to travel all over to shoot people and most, if not all of it is paid for by your sponsors.
If the top thing to aim for however is some national league, the appeal to be in the best team(s) looses a lot of its appeal. After all, you don't go to strange and exotic places. You would see all the same faces at every tournament, so what is the point in working your ass off, if you get to go to every same event, have as much fun with people who are your mates and you don't have to train three times a week to be able to do it?
Leaving the obvious economic problems aside, for paintball as a sport it would be fantastic if the pro leagues would have their own events where no other divisions would play and pretty much all sponsor money would go their way. It would certainly focus people to start doing some real training in order to maybe one day achieve that level, rather than muck around in some lowly league, but rubbing shoulders with the pros at the same time, because all teams and divisions are heaped into the same event?
One of the reasons kids aspire to become pro soccer players is exactly because of its exclusivity.
