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.

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.

The Serbs are a South Slavic ethnic group that formed in the Balkans. The majority of Serbs inhabit the nation state of Serbia (with a minority in disputed Kosovo), as well as Bosnia and Herzegovina, Montenegro and Croatia. They form significant minorities in Macedonia and Slovenia. There is a large Serb diaspora in Western Europe, and outside Europe there are significant communities in North America and Australia.

The Serbs share many cultural traits with the rest of the peoples of Southeast Europe. They are predominantly Eastern Orthodox Christians by religion. The Serbian language is official in Serbia, co-official in Kosovo and Bosnia and Herzegovina, and is spoken by the plurality in Montenegro.

The modern identity of Serbs is rooted in Eastern Orthodoxy and traditions. In the 19th century, the Serbian national identity was manifested, with awareness of history and tradition, medieval heritage, cultural unity, despite living under different empires. Three elements, together with the legacy of the Nemanjic dynasty, were crucial in forging identity and preservation during foreign domination: the Serbian Orthodox Church, the Serbian language, and Kosovo Myth. When the Principality of Serbia gained independence from the Ottoman Empire, Orthodoxy became crucial in defining the national identity, instead of language which was shared by other South Slavs (Croats and Bosniaks). The tradition of "slava", the family saint feast day, is an important ethnic marker of Serb identity, and is usually regarded their most significant and most solemn feast day.

Oceania ( or ) is a geographic region comprising Melanesia, Micronesia, Polynesia and Australasia. Spanning the eastern and western hemispheres, Oceania covers an area of and has a population of 40 million. Oceania is the smallest continental grouping in land area and the second smallest in population after Antarctica.

The islands at the geographic extremes of Oceania are Bonin Islands, a politically integral part of Japan; Hawaii, a state of the United States; Clipperton Island, a possession of France; the Juan Fernandez Islands, belonging to Chile; the Campbell Islands, belonging to New Zealand; and the Cocos (Keeling) Islands, belonging to Australia. Oceania has a diverse mix of economies from the highly developed and globally competitive financial market of Australia and New Zealand, which rank high in quality of life and human development index, to the much less developed economies that belong to countries such as of Kiribati and Tuvalu. The largest and most populous country in Oceania is Australia, with Sydney being the largest city of both Oceania and Australia.

The first settlers of Australia, New Guinea, and the large islands just to the east arrived between 50,000 and 30,000 years ago, when Neanderthals still roamed. Oceania was first explored by Europeans from the 16th century onward. Portuguese navigators, between 1512 and 1526, reached the Tanimbar Islands, some of the Caroline Islands and west Papua New Guinea. On his first voyage in the 18th century, James Cook, who later founded the Hawaiian Islands, went to Tahiti and followed the east coast of Australia for the first time.
