Mavs Previous Opponents

I didn't really watch much of the playoffs outside the Wolves, but I'm curious to know for the teams that did beat the Mavs (OKC and LAC), how were those teams able to overcome the matchups for the games they won?

It's clear we didn't play up to our standards, but I'm also starting to believe we frankly just ran into a matchup buzzsaw in Dallas. With Phoenix and Denver, it seemed to be more about containing the bigs and we had the more aggressive big men. With Dallas though, we just didn't seem to have an answer to their perimeter shooting which absolutely killed us.
