Johnson is a six-time All-Star and former All-NBA team member in large part because of his offensive prowess. He has scored more than 18 points per game and shot over 43 percent from the field for the past seven years in a row. That consistency has been a big part of his career.
The 2011-12 season was not his most prolific one as an NBA player. However, it was one of his more efficient seasons. His PER was 18.4, which is less than it has been in the past. He made up for that in part by taking less shots and missing less shots.
His 2011 true shooting percentage of 56 and effective field goal percentage of 52 were both well above the league average and his own career average. He totaled 18.8 points per game.
Anthony is a five-time All-Star and an All-NBA team member. His career has been less consistent, but his scoring runs have had higher peaks. In the 2006-07 season, he scored more than 27 points per 36 minutes.
Anthony's production has dropped off in recent years, due more so to decreased efficiency than anything else. His points per game, field goal percentage and PER have decreased for the past three years. Additionally, his true shooting percentage was below the NBA average in 2011.
One issue that has cut into Melo's numbers in recent years is that he has not adapted his game to his decreased efficiency. By decreasing his usage, he could become a more efficient player. However, his usage in 2011 of 32 percent was one of the highest in the league—seven percentage points more than that of Joe Johnson.
The style of basketball Carmelo plays—which relies on isolation and mid-range jumpers—does not work unless he is able to hit shots.
This is a close category, and ultimately it is a wash. In the past NBA season Johnson scored slightly less than Anthony while taking a lot less shots. The nearly four percent difference in true shooting says a lot, especially since Johnson is a guard and Anthony is a forward.
Both players are in for very different seasons in 2012-13. Johnson is starting with a new team, while Carmelo is playing on a roster that went through a lot of offseason upheaval. We will have to wait and see if either of the two can improve their offensive games with the help of new teammates.
Anthony will get to play with point guard Jason Kidd, while Johnson will get to play with point guard Deron Williams.
