Mark Cuban revoked the media credentials of Marc Stein and Tim MacMahon due to concerns that automated game reports could eventually replace human-generated content.

The Associated Press, in a partnership with Automated Insights, produces automated stories on minor league baseball but does not use the technology for most of its sports coverage. 

"Maybe I will be wrong but I see a direct path from the trends in coverage of games we are seeing over the last couple years to the automation of reporting on games and the curation of related content," Cuban wrote in an email to the AP. "This isn't a knock on wire services or their reporters. They are valued and valuable in sports coverage."

Cuban said he responded after learning that ESPN was relying on wire services for game coverage on 19 NBA teams. Barry Bedlan, AP's sports product manager, said ESPN "has relied on us for years."

MacMahon has covered the Mavericks primarily for several years but has spent more time in other cities this season. Stein joined ESPN as a national NBA writer in 2000 after previously covering the Mavericks for the Dallas newspaper. Both reporters are based in Dallas.
