Chris Finch knew he wasn't going to have time to completely overhaul the Timberwolves defense when he took over as head coach a few games before the All-Star break.
So for the second half of the season, the main philosophy he wanted to preach was this: Less thinking, more running.
As in, don't worry so much about the minutiae of coverages. If somebody has the ball and is open near you, guard that person, no matter who it is. If that player passes the ball, your teammates will do the same.
It requires a lot of effort and energy, since possessions with a lot of ball movement might quickly gas the players.
