(Las Vegas, NV)  --  Oddsmakers in Las Vegas say the Portland Trail Blazers have a 30-to-1 shot at winning the NBA title in 2015.  The Blazers went into the 2013-14 season carrying 150-to-1 odds, but made it to the second round of the playoffs before losing in five games to the eventual NBA champs, the San Antonio Spurs.  "The Oregonian" reports the Miami Heat are the early favorite to win it all in 2015 at 5-to-2.  Oddsmakers say the Milwaukee Bucks have the slimmest chance at winning the title at 300-to-1.
