With LeBron James now less than a week from free agency, there seems no end to ways to measure his market power.

Here’s another: FanSnap.com, a search engine that covers 45 sites selling NBA tickets, did a study of the “LeBron Effect’’ this past season.

It showed tickets to James’ home games averaged $130.28 on the secondary market, second only to the Lakers’ $242.93, despite the smallness of the Cleveland market.

And it showed that for the several teams considered most likely to sign James, there was a huge spike for his games compared to the games just before and after visits by the Cavaliers.

That increase was 187 percent for the Knicks ($192.23 for James, $67 for games before and after his), 245 percent for the Nets and 311 percent for the Bulls.
