In a culture that fosters conflict, Jonathan Martin has tried to avoid it.

Coping with day-to-day treatment he considered abusive, the Miami Dolphins tackle let the situation fester for months before leaving the team last week. Martin's agent then complained to the Dolphins, who suspended guard Richie Incognito.

The NFL is investigating whether Incognito harassed or bullied Martin, and whether their teammates and the organization mishandled the situation. In the macho world of the pro football, some players believe Martin should have responded more firmly.

Dolphins players have robustly defended Incognito, now a notorious national villain, saying he and Martin behaved like best friends. They've been less passionate in their support of Martin.
