"I knew that what he was doing in Vegas was going to end only one way, and I thought it would be humiliating for him. I tried to talk him out of it. He didn't listen," Seau's financial advisor Dale Yahnke told GQ.
In 2010, hours after being arrest on suspicion of domestic violence, Seau drove off a cliff in Carlsbad, claiming he had fallen asleep at the wheel.
"It wasn't an accident. I've been there lots of times, and it just doesn't work," former teammate Mark Walczak told the magazine.
