For a number of years now, the officials have started the season allowing lots of grabbing, pushing and letting defenders into the cylinder and we get ugly basketball as a result.
Around the FIBA break a crackdown on contact that restricts freedom of happens and offensive players are able to play some basketball.
If teams adapt well technically, which they have this year, the NBL becomes awesome to watch with the fast, free-flowing nature. Past 5-6 weeks have been some of the consistently most entertaining basketball I can remember.
Hopefully teams don't try to go back to all the grabbing because that's when the foul-a-thon games happen. Our refs are far from perfect, but the product is far better when they enforce the rules and teams adapt.
