While a number of teams near the top of the NBA championship odds have gone through roster shake-ups during the off-season, it has been a relatively quiet summer for the Golden State Warriors, who enter training camp as heavy -160 favourites to repeat as NBA champions at sportsbooks monitored by OddsShark.com.

With the re-signings of two-time MVP Stephen Curry and 2015 NBA Finals MVP Andre Iguodala, Golden State is poised to return to the court with largely the same group that won 67 regular-season games last year. The Warriors followed up their league-leading regular-season performance by winning a record 14 straight playoff contests en route to their second NBA title in three years.

However, the Warriors have no shortage of challengers to their NBA throne, including the defending Eastern Conference champions, the Cleveland Cavaliers, who sit second on the NBA championship odds at +550.

It has been a summer marked by change in Cleveland, including a blockbuster trade that sent point guard Kyrie Irving to Boston in exchange for a package centred around point guard Isaiah Thomas, who proved his mettle last spring by playing through personal tragedy during the Celtics’ run to the Eastern Conference Finals.

With Thomas sidelined by a hip injury that will delay his Cleveland debut, the Cavaliers also added veteran talent in the form of former MVP Derrick Rose and LeBron James’ former Miami Heat teammate Dwyane Wade. However, the Cavaliers will have to fend off a steadily improving Celtics squad that closely trails them as a +800 bet to claim their first NBA title since 2010.
