A view from the other side of the pond
OK, Sid, try this out--
The tendency used to be and still is to a lesser degree to scout for talent among proven teams and in your own backyard. So guys who play the same places and are regularly seen by the "pros" have a huge advantage and they are the ones who get tapped most often. (And by seen I mean seen in a competitive environment not just hanging out playing some rec-ball) Also, "pros" used to assume that if your team wasn't top notch then the players couldn't be either so lots of quality players didn't get considered cause nobody gave them a second look.
It's a bit different now with the explosion in the numbers of competitive teams and the shift to concept fields because the pressure is even greater to be on top and stay there and the success some am and nov teams have had against the pros has given them something to think about whether they like it or not.
On an individual basis you have to be damn good, frequently better than some of the guys playing that level now cause they're already there and you're not. The other individual factor is your mental game. There are plenty of players with "pro" level technique but without a "pro" attitude and on the flip side I've seen more than a few "pro" players who don't have the technique but have the attitude. You also have to be willing and able to make the necessary sacrifices to dedicate yourself to the game. At this stage it doesn't matter how much stuff you're given there are still alot of things you must give up, primarily time and the other choices you could make.
After all that, in order to have a chance a number of things have to be in your favor-- pro team's needs, face time and fit. If you're a front guy and the captain is focusing on filling a back slot, oh well; and you have to be where you can be seen, often (play the events they play); and last but not least you need to have the right fit, be comfortable with and get along with the existing team.
Bottom line is you need to be prepared to market yourself if you really want it. It's a competitive market in more ways than one and maybe being in Scotland just won't cut it.
That turned out longer than intended (but nothing unusual in that.)
