I dont think it makes you greedy Kap.
The thing about members not sharing numbers here is fine, but IMHO, I dont think it makes much difference if someone does or doesnt post their numbers. I think people are "afraid of the Boogey Man"
Mink pointed out nobody that posts here played Cajun's winning set of 5. There was one winner that day, and it was a QP. Most T5 jackpots are won by QP's. That's because more QP's are sold than player picks. (It's 3 to 1 in favor of QP's) QP's are the thing that you cant control. While it's true that single JP winners do happen, the reality is that T5 JP's are split among multiple winners more often than not.
As far as playing someone else's numbers I see posted here, mostly I dont do it. (I lived to regret that the day The Cajun hit the ball out of the park.) Why dont I do it? Because my analysis differs from someone elses most of the time. When I see numbers other have posted, I try to figure out why they like them. Some times it's obvious to me why they like them. Other times it's not so obvious, and my inclination is to dismiss their picks entirely. I suffer from the "Aw what the heck does he/she know?" syndrome and I'm willing to bet most people are just like me in that regard. I'm biased towards MY picks. They're biased towards theirs.
For instance, I analyzed the numbers Billbo posted that he said never change. I saw things about them I didnt like. That doesnt mean his numbers arent any good, it simply means I wouldnt play them all the time like he does. But they're Billbo's personal choice, his picks are just as good as mine or anyone else's. All that matters is Bilbo likes them, and he has his own personal reasons for that. Hopefully he'll win a JP with them.
