Does it take a freaking defensive scheme to get a player to stay in front of his man? Does it take one to get a player to get a hand in the shooters face? Does it really take a defensive scheme to get a player to hustle back on defense? Do you need a defensive scheme to get a player to actually close out on shooters and challenge shots?
We don't need a new defensive scheme, we need players that PLAY DEFENSE!! Until we see them putting forth some actual effort they are purely and singly at fault for our defensive woes.
This is the equivilent to saying in Football...
"Does it take a defensive scheme for DBs and linebackers to cover the receivers?"
The obvious answer, YES!
In basketball, VERY FEW players can actually stay in front of other players. One on one, no one in the NBA can cover the opposing player. Not legally anyway.
The cure is deception and scheming to funnel players into places they don't want to go.
Deception... Act as if you're going to press and bail.
Act like you're in a zone when you're not.
Act like you're in man when you're not.
Act like you're going to double team then bail.
Quickly bring a trap.
Keep opposing offenses guessing when you're going to "blitz" and who's coming is critical for football. Why not in Basketball?
As far as funneling, the Jazz don't do any of this. We let the offense dictate to us where we, the defense, go.
Seriously, why don't the Jazz force someone else to bring the ball up the court? Keep the ball away from Rose. Press, trap, deny him the ball.
Force a guy baseline and trap him. Force guys like rose to their weak hand. Front big men in the post. Switch matchups. Switch on screens sometimes.
The Jazz don't do any of that.
Seriously, the effort is lacking at times. But the defensive scheme is completely non-existent. What are the Jazz trying to accomplish? There needs to be specific goals, since every defense in the world is geared to "stopping" the other team from scoring. But specifics are greatly needed for a top defense. The jazz don't have any goals or specific plans. As a result, they look like one disjointed group of defenders watching opposing players score on them at will.
