Exactly. I don't know why so many people are so committed to assigning blame literally anywhere but with Tyreke.
Tyreke has flaws in his game and he can make poor decisions at times. But to say that the play of his teammates have no impact on Tyreke's game is not an accurate statement. The play of Tyreke's teammates, especially the wings ability to knock down an open shot, plays a huge part in how well Tyreke will play in the game.
It's all actually quite simple. Tyreke's best skill is his ball-handling and ability to drive to the basket. People still consider him having the ability to run the team because he can do a great job of finding the open man on the wings (and especially the corners) when he drives into the lane.
So let's consider two different scenarios.
Scenario 1
Tyreke drives into the lane, the defense collapses on him, but they are not able to collapse quickly enough on him due to their proximity to the wing players and he is able to score at the rim. (2 points)
2nd time down the lane, the defense this time plays a bit off of the wing players, and when they collapse, it leaves a wing player wide open in the corner. He passes it to the corner and the SG/SF airballs the open 3pt corner shot. (1 assist lost)
3rd time down the lane, the same thing happens. The defense hedges away from the perimeter, clogging the paint, the pass goes out to the open wing, who misses the wide open shot. (Another assist lost)
4th time down the lane, Tyreke is tired of his teammates missing wide-open shots, so he forces a tough shot in the lane and misses. (Poor FG attempt)
As long as Tyreke's teammates are unable to hit open shots it takes away driving lanes from Tyreke, reduces assist totals, and creates situations where tougher shots are going to be taken.
Now contract the Scenario 1 to Scenario 2
Scenario 2
Tyreke drives into the lane, the defense collapses on him, but they are not able to collapse quickly enough on him due to their proximity to the wing players and he is able to score at the rim. (2 points)
2nd time downt he lane, the defense plays a bit further from the wings to collapse the paint on Tyreke, Tyreke hits the open man on the wing who then knocks down the corner 3. (2 points + 1 assist)
3rd time down the lane, the defense plays the wings more honestly, leaving a lane open for Tyreke who then finishes at the rim. (2 points)
If you're not able to see how a teammate's ability to knock down the open shot greatly impacts Tyreke's game, then I'm not certain what can be said. If his teammates are playing poorly, it allows the defense to load up on Tyreke. If his teammates are playing well, it forces the defense to make a choice on which 'poison' they will select, either load up on Tyreke and have him rack up assists as his teammates hit the open shot, or play the wings honestly, thereby giving Tyreke a better lane to the basket.
This is the same situation that Dwight Howard is in. If the team defense decides to double-team Howard everytime he gets the ball in the post, because his teammates are missing all of their open shots that he gets them, then Dwight will have a much tougher game than if his teammates were knocking down all of their shots.
Basketball is a team sport and how well a player plays has a lot to do with the performance of other players. In this case, Tyreke becomes a much better player when his teammates are hitting open shots.
