While Mike Tomlin has been one of the best coaches in the NFL, he’s also apparently been the league’s most lucrative “Minecraft” builder. 

Tomlin opened up about solo-building a private world on his YouTube channel, which he says he began 12 years ago. 

The Super Bowl-winning former Steelers coach showed off his impressive “Minecraft” world, complete with a community on a lake, high-rise apartments, an aquarium filled with different types of fish and vast areas of trees and greenery.

“The crazy part is how much time it took me to get that water situated,” Tomlin said in a stream on his YouTube channel. “It was a nightmare. This apartment building right here next to the aquarium. For whatever reason, I would get fixated on bedrooms.” 

Having begun this hobby in 2014, Grok estimated that Tomlin’s “Minecraft” obsession has taken at least 2,000 hours to get to this point. 

“Sometimes buildings have themes,” he added. “I was always view conscious of these high-rise buildings.” 

Tomlin couldn’t even cover his entire world in a 20-minute video he posted, adding that he will need to show off a soccer stadium in another part to be posted later.

The NFL broadcaster for NBC added that he’s always been interested in architecture and building things while discovering new things about himself in the process, with different obsessions over little intricacies and details.

The 2,000-hour projection sounds like a lot, but it averages out to roughly six hours per week over 12 years. 

His son, Mayce Tomlin, posted on X that his dad would swipe his gaming console without notice to work on his community. 

“Bro, I used to come home sometimes, and my PlayStation would just be gone. And I wasn’t in trouble,” Mayce said in an X post with multiple laughing emojis. 

Tomlin figures to show off more glimpses into this world in future episodes.
