Unless your opponent gets lucky and pulls a team that can all shoot lights out, it's very viable. I win 90% of my games when I play off-ball defense on their weakest shooter and just camp in the paint (no defensive 3 second violation!), then on offense post the living **** out of them with Nurkic or Marjanovic (no offensive 3 second violations either muahahaha). Either drop-step or post-spin. It must be absolutely humiliating to get destroyed by someone who looks like a cave troll lmao.
You do have to keep an eye out for that ****ty automatic help defense that leaves people wide open for three's, but honestly it's not that hard. Defending 3 people is a lot easier for me than defending 5.
Slashers are also incredible in blacktop. Players like David Thompson, Reggie Lewis, Amy Kobe, Eddie Jones, Paul Pierce with a SWB shoe are all basically guaranteed wins if you play them right.
Another thing that's
IMMENSELY fun in blacktop (and honestly in full games) is doing "katana" lobs. I will be eternally grateful to Sam Pham for showing me how to do this with very clear instructions here:

I've had games where literally 15/15 points were from lobs. It's honestly ridiculous how well it works once you get it down. I sometimes even forego calling the screen and just pass to one of my guys down low, let him hold the ball, and then toss it up whenever the player I'm controlling gets near the basket. It leads to incredibly exciting and cheesy moments like this:

Nothing is more satisfying and erection-producing than ending a game with a lob. And if you have any players with HOF Lob City Finisher, the cheese is multiplied by a factor of 69. Lobs like this are commonplace for my Stoudamire, Kenyon Martin and Deandre in blacktop:

This one made me laugh out loud:

Also, I honestly have no idea if the 3pt patch has affected blacktop. I've been playing blacktop since this game came out and I haven't noticed much of a change, but I could be wrong.
