Why Do Some Caddies Stay Loyal To Their Golfers In Your Opinion?

Do you think that loyalty is really that important between a Caddy and a Golfer? How much of a difference does a Caddy make for a professional Golfer in your opinion? Why do you think that some Caddies turn down other jobs especially if its from a better player? Like in Tony Navarros case. He had a great opportunity to Caddy for Tiger Woods in 1999. But he turned it down for some reason. I think that any Caddy who had the opportunity to work for Tiger Woods should have taken it in my opinion. I don't get why Tony Navarro turned down a golden opportunity to Caddy for the greatest Golfer of all time. I bet he probably is kicking himself now. How many of you would Caddie for Tiger Woods if you had the chance? I know that I would definitely jump at the chance to Caddy for Tiger Woods. I would just tell my other player that I got a better opportunity/offer. I don't think that any Golfer would be mad at their Caddy if they had an opportunity to work for Tiger Woods. If anything most Golfers would encourage and want something better for their Caddies. I would love to hear everyone's opinion about The Golfer and Caddy Relationship and why you think loyalty is or isn't important.
