Since Roger Goodell took over as NFL commissioner in September 2006, he's had his hands full. 

The current domestic violence case involving former Baltimore Ravens running back Ray Rice is just the latest in a long list of controversies that have punctuated his reign atop the country's most profitable sports league. 

Here are some that have attracted the biggest headlines: 

Michael Vick's dog fighting arrest 

Allegations of Vick's participation in dog fighting activities began to swirl in April 2007. 

Within three months, the Atlanta Falcons quarterback and three associates were indicted in federal court. 

By the end of August, Vick reached a plea agreement with federal prosecutors on one charge of conspiracy involving illegal dog fighting. Vick admitted participating in killing dogs and operating a business enterprise that involved illegal gambling. 

Goodell notified Vick that he was suspended from the National Football League indefinitely, without pay. 

Vick served 20 months for the conviction. 

In 2009, Goodell reinstated Vick to the league on a conditional basis. In 2011, he signed a six-year, $100 million contract with the Philadelphia Eagles, making Vick one of the highest earning players in the NFL. 

Vick is now a backup quarterback for the New York Jets. 

Plaxico Buress' nightclub incident 

The former New York Giants wide receiver accidentally shot himself in the leg with a .40-caliber semiautomatic pistol he was carrying in his waistband. The incident happened November 2008, in the VIP area of the Latin Quarter nightclub in Manhattan. 

Buress served 20 months on a weapons charge.
