Ndamukong Suh swears he isn’t superstitious, but he’d prefer not to jinx things. That’s why he’s being so coy.

Sitting in Seattle-Tacoma International Airport, waiting to catch a flight, he’s asked to relate a few of his success stories. Specifically, the ones that have nothing to do with football.

Unbeknownst to many football fans, the Miami Dolphins star defensive tackle has established himself in the world of big business, actively pursuing profits just as feverishly as he does quarterbacks.

Mentored by billionaires and motivated by more than just money—because, let’s face it, he already has plenty—Suh is aiming to be remembered more for the legacy he builds off the field than for the plays he makes on it. Just don’t call him a mogul in the making.

“I stay away from 'mogul' because moguls are people, in my opinion, [who put themselves] out there,” says Suh. “In my business, I’m very, very private. I like to be behind the scenes.”
