Why were Terry Stotts and Doc Rivers yelling at each other?

During Thursday night's memorable preseason game between the Los Angeles Clippers and Portland Trail Blazers (a game that saw L.A. come back from a 35-point deficit to win), things got a little testy.

Blazers head coach Terry Stotts and Clippers head coach Doc Rivers were both swept up in the emotional game, and some words were said. Or, more accurately, screamed. Words were screamed. 

Here's video of what each coach had to say afterward about the incident, per CSNNW:

A 35-point comeback is a 35-point comeback, but at the same time, it's the preseason. And one team has its eyes on the championship while the other is headed for the lottery. Everyone should probably calm down.
