That's just one of the great performance of the Timberwolves and the reason why they are on the top seed right now. We've seen a lot of crazy comebacks from a lot of different teams most frequently this season, this is just an indication that there are actually no leads are safe until the game concluded. Just most recently Dean Wade made a crazy fourth quarter to come back from a 20+ pts deficit in the 4th and win the game. That was just a few games after LeBron took over the 4th quarter to beat the Clippers in another comeback win.
These are all because the game of basketball today are more fast paced and everyone can shoot 3s more efficiently than before. A 20+ pts lead even in the 4th quarter isn't really safe nowadays. It will only take 1 player in the zone and extra effort on the defensive end can make a comeback win.
It was the defense that really helps the Wolves to outrun the Clippers, like what you mentioned, even a double digit lead in the final quarter ain't safe anymore, as players can hit high percentage shots and play good defense to turned the tempo of the game and snatch the win, another monster performances of ANT but I think what I love is seeing how the coach blends players inside and how they are doing their respective roles in helping each other, even how good ANT might be without the help of everyone he won't be able to single carried the team and win the game.
They are performing and the way they are forcing the defense that's something that will help them to reach the playoffs and hopefully with KAT recover back they might have a good shot to move forward.
Too early for that though, just need to be consistent and keep the competitiveness to win more games during the regular season.
