NBA - Main

I was looking at the In season tournament standings and to me it looks like there could be a lot of tie breaking needed(especially for the wildcard teams). Head to head is the first tiebreaker, but it looks like this is not going to work everywhere (for example all of west group c teams could easily finish 3-1 with wins against each other).

The way I understand the wildcard is that the the top 2 teams that don't win their groups will be chosen, but there will be like 4 of those with tied records as well, so they will go to point differential. So we are basically choosing the teams based on who ran up the score against the wizards, spurs and grizzlies the most? Doesn't encouraging running up the score seem kinda dumb? Sorry if I misunderstood the format I'm just trying to figure it out.
