Firstly, the bolded part, there has been a lot of talk here in Sydney that clubs are beside themselves with the content of the blueprint. Shane Richardson himself has had to go on record to backtrack a bit by claiming its just a discussion piece and is glad he's copping the criticism as that was the intention of it.
Your point about the draft, lets look at 2000-2010 at top 5 picks.
2000-Kenyon Miles, Stromile Swift, Darius Miles, Marcus Fizer, Mike Miller - not a single star or game changer there
2001-Kwame Brown, Tyson Chandler, Pau Gasol, Eddy Curry, Jason Richardson - Chandler has had about 2 good seasons, Gasol is good, the others are horrible
2002-Yao Ming, Jay Williams, Mike Dunleavy, Drew Gooden, Nikolaz Tskhitishivli - Yao Ming aside, none of them turned clubs around
2003-LBJ, Darko Milicic, Melo, Bosh, Wade - 4 great players here, 1 flop
2004-Dwight Howard, Emeka Okafor, Ben Gordon, Shaun Livingston, Devin Harris
- Dwight Howard aside, thats a pretty ordinary lot isn't it
2005-Andrew Bogut, Marvin Williams, Deron Williams, Chris Paul, Raymond Felton - CP3 easily dominates here, Bogut is a handy role player, Williams had 2-3 good seasons
2006-Andrea Bargnani, LeMarcus Aldridge, Adam Morrison, Tyrus Thomas, Shelden Williams - Aldridge is a very good player, not elite I would say though. The rest, horrid
2007-Greg Oden, Kevin Durant, Al Horford, Mike Conley Jr, Jeff Green - Durant is outstanding, Horford is good, Conley decent
2008-Derrick Rose, Michael Beasley, OJ Mayo, Russell Westbrook, Kevin Love - Rose, Westbrook and Love are outstanding, the other two are serviceable journeyman
2009-Blake Griffin, Hasheem Thabeet, James Harden, Tyreke Evans, Ricky Rubio - Griffin and Harden are outstanding, Evans is a decent journeyman, Rubio is a good passer but limited elsewhere
2010- John Wall, Evan Turner
, Derrick Favors, Wesley Johnson
, DeMarcus Cousins - Wall is a very good point guard, Cousins is a troubled by very fine centre, the rest are journeymen at best
So there you have it. The draft is not the be all and end all that some think it is to distribute talent. Off the top of my head, Miller (as a role player), Gasol, LBJ (but not with his original club), Wade, Bosh (but not with his original club), Bogut (as a 3rd or 4th best player in his team) have won an NBA championship. The rest have not. If we go by #1 picks during this period, you have Washington x 2, the Clippers, Bulls, Portland, Toronto, Milwaukee, Orlando, Cleveland, Houston and the Nets who have gone #1. The Bulls have won the NBA in this period. Aside from Cleveland last year, if memory serves the others have not played in the NBA Finals series. Some of those teams like Orlando, Portland, Toronto, Washington and Brooklyn have frankly struggled to regularly get to the playoffs (of which half the teams make the playoffs every year).
On the crowds, you can talk about sport in general as much as you like, frankly. But its a tell tale sign when Wayne Scurrah, who definitely tried to diversify our revenue streams away from crowds, spoke ad nauseum over and over on the record about break even crowd figures and how poor attendance affected the club financially. If they're only worth 10% of the revenue, certainly you'd throw your focus well and truly on other areas. For sports like the American sports or the EPL with massive, monstrous television deals, outrageous merchandise sales, and unparalleled sponsorship monies, yes you can point to crowds being a small portion.
