Magic and Michael

Posted on June 25, 2007 by


Who’s the Best? This one question sparks the most fervent debate among sports fans. Was Willie Mays better than Mickey Mantle? How does Barry Bonds compare to Ken Griffey (or Babe Ruth, or Sammy Sosa, or whoever)? Is Joe Montana better than Dan Marino? Is it Wilt or Russell?

A few weeks ago I responded to a Bill Simmons observation that Tim Duncan is clearly better than Kevin Garnett. My argument focused on the quality of teammates each got to play with and concluded that these two players, despite very different team outcomes, were actually quite similar.

Today I want to focus on two great players who had very similar team outcomes: Magic Johnson and Michael Jordan. Magic and the LA Lakers went to the Finals nine times, winning five titles. And as noted previously, Magic was the most productive player on those teams. MJ took the Bulls to the Finals only six times, but his team won all six times. And as detailed yesterday, His Airness was the most productive player on those teams. But which of these two players was “better”?

For our answer, let’s turn to The Wages of Wins metrics (were you expecting a different approach?).

Here is Magic Johnson’s career performance in terms of Position Adjusted Win Score (PAWS), PAWSmin, Wins Produced, and Wins Produced per 48 minutes [WP48].

Table One: Magic Johnson’s Career Productivity

Magic played thirteen seasons and produced 316.5 wins, for an average of 24.3 wins per season. His career WP48 stood at 0.457. To put those numbers in perspective, Jason Kidd led the NBA in Wins Produced in 2006-07. Kidd’s final mark was 24.8 wins and a WP48 of 0.405. So Magic’s average season is better than anything we saw in 2006-07.

Now let’s look at Michael Jordan.

Table Two: Michael Jordan’s Career Productivity

Jordan played 15 seasons before finally retiring at the age of 39 in 2003. Across all these years he produced 289.6 wins and posted a 0.339 WP48. Of course these numbers are brought down somewhat by what he did after both his first and second retirement.

If we only consider MJ’s first nine seasons, before he went to give baseball a try in 1993, we see a much higher level of production. At the end of the 1992-93 season Jordan had produced 213.1 wins, for an average of 23.7 per season. If we ignore the 1985-86 campaign where he only played 18 games, his per season average rises to 26.4 wins. His WP48 before the first retirement was 0.396. In terms of Wins Produced, his average was better than anyone this past season, although his average WP48 was just a tad below what Kidd offered.

Of course we are not comparing Michael to Kidd, but rather, Michael to Magic. When we consider both players in their prime we see that each was extremely productive. It does appear, though, that Magic was just a bit more productive. Magic’s average WP48 hovered around 0.450 while MJ is closer to 0.400. Both are amazing numbers. But Magic is a bit higher.

Of course we want to know, why are we getting this result? Here are three possible explanations.

1. Wins Produced is based on box score statistics. This metric does include defense, but only at the team level. In other words, defense is incorporated for each player in terms of how well his team plays defense (a couple of months ago I experimented with using data to improve on this approach, but the player evaluations seemed quite similar). Now if Jordan was a much better defender than the average Chicago Bulls player, then Wins Produced understates his contribution. Likewise, if Magic was a much worse defender than the average player on the Lakers, his contribution is over-stated.

It’s important to note, MJ must be much better than the average player on Chicago, not the average player in the league. Although we have no data on how well these players played defense, it does seem to me that many of the Bulls players were pretty good defenders. So it seems unlikely that MJ was immensely better than his teammates, but it’s possible.

2. In calculating WP48 for Magic I used the relationship between PAWSmin and WP48 in every year except 1980-81, 1986-87, and 1995-96. In those three seasons, I used the more extensive approach detailed in The Wages of Wins. This approach explicitly incorporates team defense and hence tempo, and is a bit more accurate measure. It’s possible that Magic’s numbers would be lower if I used the more extensive approach in every season, as I did for MJ in every year except for 1984-85 to 1987-88.

3. Maybe it’s not team defense or how WP48 is calculated. Maybe when all is said and done, Magic is just a bit more productive than Jordan.

Whether you like Magic or Michael, we do see in the data that each player, in their prime, is better than any player playing today. The two best players over the last decade are Tim Duncan and Kevin Garnett, and neither of these players comes close to Magic or Michael.

Of course that might be because the average player in the past ten years has improved, and hence the very best cannot move so far from the average anymore. Okay, that’s something that needs to be talked about another day.
