Have you recovered from the throbbing hangover that you've experienced every waking moment of your life since the Mavericks lost Game One? Let's hope that you have. Drink more water if you haven't. Might I also suggest a La Croix or Topo Chico? You'll be feeling better in no time...as long as you don't think about it. Just forget that it happened.
Unfortunately, I'm about to talk about it. Sorry.
What adjustments do the Mavs need to make?
Honestly, there are far too many to address in a short preview. However, the main concern should be on defensive positioning.
