IT is 18th in the NBA in scoring. He averages less shots than everybody above him except for 1 person (15.2 to 15.0), including every PG. His shooting percentage is also higher than every scoring PG above him except the number 1 guy, Steph Curry (IT is the 7th best shooting PG in the league). Not only is your statement inaccurate, it is actually the opposite of the truth.
Here's the problem here.
Okay, right now IT is 20th in the NBA in FGA/48 (at least amongst major scorers) at 21.6. That is the same number LeBron takes, more than Lillard or Harden (but of course Harden gets to the line) but at least he's not gunning like Kyrie.
Now the problem is, that's season long. And the REAL problem is that Isaiah has been sliding toward more one diminesional I'm just a scorer play month by month.
here was IT's per 48 numbers in November, when he came off the bench as a gunning 6th man:
NOV 21.2FGA 3.9reb 7.6ast 1.6stl
now his 3 months as a starter:
DEC 21.1FGA 4.1reb 10.3ast 2.5stl
JAN 22.3FGA 3.7reb 8.7ast 1.5stl
FEB 23.0FGA 3.3reb 6.2ast 1.3stl
From that high in December, while he was still gunning but seemed to be making an attempt to pass, he's slowly been degrading in every way except he's gunning up more and more shots. 22.3FGA/48 moves him into 16th in the entire league. 23.0FGA/48 moves him into 12th. Meanwhile his 10.3ast/48th would have been good enough for 9th in the league. But 8.7 is only 20th, sandwiched between Jamaal Crawford and Kyrie Irving, and 6.2 ties him for 40th in the NBA with his mentor, Nate Robinson. Its all trending the wrong way.
He's taken 20 or more shots in 6 of the last 9 games. And the rub of it is this:
IT in wins: 13.6 FGA, 7.2ast
IT in losses: 16.1FGA, 5.6ast
We are 0-8 this year in games where IT guns up 20 or more shots. We are 0-11 this year in games he guns up 18 or more shots. We're 17-22 in games where IT shoots 17 times or less.
The selfish little gunner act isn't helping his team. It may be helping IT, or his ego, or he may think its helping his contract push, I don't know. But its not helping us as a team. What helps us as a team is when he recognizes his role, steps back, sets up teammates and functions as a sidekick, not the guy leading the team in FGA. If his ego clouds his judgemnet on that matter, then the coaches have to get it through to him.
