I can understand your confusion as the conversation has meandered off course a bit.
I was trying to show that Johnson creates a lot of his own shots based upon how I define the term creating one's own shot. That he creates his own shot in more of a variety of ways and different ways than Baragnani does.
As I recall you or someone else said that we can expect Bargnani to get more of his shots in the paint with Bosh gone then with Bosh in Toronto.
My response was that I don't agree with that position because Johnson and Kleiza will take most of the shots in the paint. In the process especially Johnson because he takes so many of his shots at the rim that when Bargnani plays on the court with him vs Bosh he gets more "open" spot up shots. Since that is what Bargnani shoots the most of and because he can score from beyond the arc therefore he will take just as high a percentage of his shots via the spot up jump shot in 10-11 as in 09-10 if not a higher percentage of them. As a result he will be open more often and take fewer contested spot up shots and that as a result his spot up shooting percentage will also go up in 10-11 vs 09-10.
Then somehow we got sidetracked into the effectiveness of the isolation play which everyone agrees is a creating your own shot play vs scoring off of an offensive rebound which I contend is creating your own shot. Why because
1. First you have to get the rebound
2. Second you have to then be able to create a shot off of that rebound.
Most players can not do that and do it well. Johnson needs to improve his 64% FG% on put backs from last season. I would like to see him get it up to 70% with a bunch of and-ons included. Even if he can ever do this it will take time and experience to learn how to be able to draw the contact get fouled and make the put back shot with a high degree of accuracy like Howard can. I am not saying that Johnson will ever be able to do it. I am just saying this is something he should work on and try and achieve.
Then we meandered even more into comparing the effectiveness of an ISO play vs the effectiveness of scoring on a put back shot. I contend when comparing the put back shot to the ISO shot.
1. Put back shots result in higher PPP then ISO shots
2. Scoring off of a put back shot is what people call second chance points
3. That it is highly beneficial to a team to have a plus differential in second chance ponts
4.
That the ISO shot is over rated and one of the less effective in terms of creating your own shot and in PPP.
5. Fans love the player who can create his own shot and over rate it because it is an exciting play even if it is not a particularly efficient one in terms of points per possession.
6. NBA coaches and players have come to the conclusion that the only way to be relatively effective in scoring; i.e having a high PPP on ISO shots is for players to get to the free throw line a lot when they create their own shots in this manner.
That is why the players who use the ISO shot try to draw a foul as much as they try to make the shot. They realize that over a game and a season that the ISO play unless accompanied by a foul shot a good deal of the time is basically one of the least effective shooting plays in basketball in terms of field goal percentage and points per possession.
Fans and the media love the player who can create his own shot off of the dribble even if it is one of the least effective ways to try and score because it can be so exciting when a player does score off of an ISO play. Whereas no one really gets excited about someone scoring off of a put-back unless they really slam it like Howard does. Therefore writers, the media and fans tend to fall in love with the beauty of the play and not the results.
It is like the line from a song that Harry Belafonte used to sing. If you want to be happy for the rest of your life make a ugly women your wife.
