This current playoffs is a perfect illustration of how the Kerr system (built around Steph/Dray) wins championships and excels in the playoffs
Mobility over length
Kerr values mobility over size, hence why you often see multiple guard lineups. Cavs last night had 2 bigs and a a giant wing (Wade) and no mobility - and hence could not aggressively double Brunson and recover.
Kerr would have done far better even with his 4-guard lineups because Podz/Moody/GP2/Steph are all far more mobile and can run around. Also why Kerr sometimes doesn't close with Gui because Gui isn't as mobile and rotates far slower.
Teach role-players to make decisions
We just saw multiple playoff teams fizzle out when the ball was taken outta their star's hands (look at Pistons/Rockets when the ball isn't with Cade/KD). All season long, Kerr forces players like Podz/Gui/Moody to learn to make decisions taking the ball outta Steph's hands.
Versatile rim protectors
Regular season beasts like Pistons/Houston/Cavs have great rim protectors who can eat up rebounds and do well at the rim. Yet those same bigs cannot play aggressive schemes and that removes options off the table in the playoffs.
Duren/Allen/Sengun cannot hard hedge or trap consistently but Dray can. And in the playoffs Duren/Allen can become a liability against certain opponents.
We have notched wins against OKC/Spurs in recent seasons
We literally won 2 against Spurs this year. And won 2 against OKC the yeaar before that.
Kerr still has us competitive on the right nights against these monsters.
To conclude
Kerr is one of the GOAT coaches. If we had a better GM, we'd still be in the mix. There are creative things we could do, but if we never wanna trade any players/picks, it is difficult to build a roster.
I'm hoping we can pull out a good roster because Steph/Kerr deserve it.
