Bullshyt.
Let's just take shooting.
Kawhi leads the fukking NBA in 3pt-shooting right now at 48%. And that's taking 4 a game too. 90% of the NBA isn't shooting 48% on their threes even if you leave them wide open on every shot.
Kawhi is shooting 88% on free throws right now. That's top-10 in the entire league. Only forwards above him are Dirk and Durant, two of the greatest-shooting forwards in NBA history.
It doesn't matter how good your teammates are, you ain't shooting 48% on threes and 88% on free throws unless you have some serious skill. Especially as a forward.
Then add in the defense...you can't watch the man play and not realize that he is one of the greatest, if not the the greatest perimeter defender in the game right now. Coaching helped make that happen, but coaching can't turn just anyone into the #1 vote getter on the All-NBA Defensive team, and whether coaching helped him get there or not, you can't deny that that's where he is.
If "anybody" could do what Kawhi is doing right now with the right coaching, then when hasn't HOFer Ginobli ever had a season like this in all his years with Pop, Duncan, and Parker?
Right now, Tony Parker is an aging and average point guard playing 27 minutes/game and Duncan/Ginobli are off the court more often than they're on it. Aldridge is averaging 17 and 8 in 30 minutes a game. The 2nd-most played lineup for the Spurs doesn't even have Duncan or Ginobli in it, and Kawhi's still dominating whether they're on the court or not.
You can't seriously claim, "Kawhi is a dominant defender because he gets to be on the same court as Parker and Aldridge".
