I don't know if you guys spotted this news, but this upcoming NBDL season has some pretty significant rule changes.

To put it simply, 3-pointers will not count until the last 3 minutes of regulation or overtime (they'll just be regular two-point buckets). And the 8-second halfcourt rule is now 7-seconds.
The NBA claims they have no plans to institute these in the normal league, but they admit that they're using the NBDL as a "laboratory for the game in general."
How do you think those changes will affect the game?
