Three weeks into the NBA campaign, the Golden State Warriors have been unstoppable.

Closing in on the NBA record for most wins to start an NBA season by a defending champion, the Warriors improved their record to a perfect 12-0 on Monday night with a narrow 115-110 victory over Toronto, but have yet to emerge as favourites to repeat as chaps, now that NBA betting is underway at Betway.com, where they trail the Cleveland Cavaliers with 7/2 odds.The website offers a host of betting options on NBA and NCAA basketball, including game lines, props and futures betting.

Struggling for respect is nothing new for the Dubs, who opened last season well back of the leaders, with 20/1 odds, despite winning 21 of their first 23 games.

But with injuries to LeBron James sending the Cavs into a midseason tailspin, Golden State would eventually overtake Cleveland on the NBA championship odds in February, and remain in a see-saw battle with their Eastern Conference through to their showdown in the NBA Finals.

Soon after falling to the Warriors in the Finals in six games, Cleveland again emerged as early favourites to claim their first-ever league title, and wrap up the first three weeks of the season as strong 11/4 favourites at Betway.com.

The Cavs have produced mixed results in the early going, recording straight up wins in eight of their first 11 contests, but have been a dismal failure at Betway.com’s online sportsbook.

Cleveland has lost eight straight against the spread, and have seen point spreads favouring them consistently diminish, even in clashes with last season’s Eastern Conference weaklings, including the New York Knicks, and the Detroit Pistons, who recently shocked them in a 104-99 loss.

The Atlanta Hawks, meanwhile, have fuelled a rise in their NBA betting odds with a solid 8-5 start that has kept them in striking distance of the Eastern Conference-leading Cavaliers.

The Hawks finished atop the East last season with 60 wins, and advancing to the Conference Finals, where they were swept by Cleveland. However, that performance did not translate into strong opening odds at Betway, where Atlanta lagged well back of the favourites at 50/1.

Atlanta wraps up the first three weeks of their campaign amid a three-game losing streak, but now sit as an intriguing 25/1 bet to claim their first NBA crown since relocating from St. Louis in 1968.

The perennial favourite San Antonio Spurs are again in their familiar position near the top of the odds at 4/1, ahead of the Oklahoma City Thunder at 7/1, and the Los Angeles Clippers, who round out the list of favourites at 9/1.

The Chicago Bulls and Houston Rockets maintain strong 12/1 and 16/1 odds, respectively, well ahead of the Memphis Grizzlies and Miami Heat, each at 33/1, while the Raptors sit alongside the Washington Wizards at a distant 40/1, despite sporting heavy 2/7 odds to win their third straight Atlantic Division crown.
