Photos: 2017 Six Nations guide Wales' prospects – Gatland's team scored a tournament-leading 17 tries in 2016, and will have even more incentive this year. The Six Nations has followed other competitions by awarding a bonus point to teams that score four tries in a game, and also for losing by a margin of seven points or less. Points for a win or a draw have doubled to four and two respectively. Hide Caption 8 of 24

A subsequent win over Australia gave hope that Schmidt's side could again be a Six Nations contender. Hide Caption 12 of 24

Photos: 2017 Six Nations guide Scotland: 2016 -- 4th place – Last year Scotland won two matches -- more than the two previous seasons combined. The 15-9 loss at home to "Auld Enemy" England was followed by a battling 27-23 defeat in Wales before wins against the two teams that would finish below the Scots in the table. Hide Caption 13 of 24

Photos: 2017 Six Nations guide France: Coach Guy Noves – The former France winger, 62, is hoping to emulate his outstanding results from 22 years in charge of club side Toulouse. He took over after the 2015 World Cup, and the team is still far from its past glories -- though close defeats to Australia and New Zealand in November gave some encouragement. Hide Caption 18 of 24

Photos: 2017 Six Nations guide France: Home venue -- Stade de France – The 80,000-capacity ground, north of Paris in Saint-Denis, is the sixth largest in Europe. Also the host of soccer's 1998 World Cup, it will continue to host both sports after new French Rugby Federation president Bernard Laporte canceled his predecessor's plan to build a new $620 million stadium in Ris-Orangis, 35 km from the capital.
