Most of the above comments are negative. I like the idea but have always wondered at the smarts of risking injuries etc, too.
How's this, for outside the box type of thought.
Add it (All Star Event) to the pre season schedule, say the last week/weekend, with players selected on pre season form ..
.. make it a pre season, touring event going to non-NBL centres, with say 5 All Star starters and 5 more local nbl players as bench in each team. Say Sunny Coast as host, benches could be Bullets players who aren't already in. For Newcasttle, Sydney and Gong players etc.
Expensive? Definately, yes. But we are all witness to LK putting his money where his mouth is (all been for the good of the game, IMHO [suck,suck]). LK, how about some money where My mouth is? Please?
The promotion to get bums on seats could be awesome and for those who won't/can't go that extra distance to get to regular season NBL, bet you that a lot would be watching the telecasts.
