From the data we were able to find, the 2015 Atlanta Hawks set the all-time record of games covered in row with a streak of 15 in a row. The Utah Jazz are currently on an 8-game winning streak, covering the spread in every single win. In the first game of the streak they were +5.5, otherwise they have been favored in every game. To tie the record they will need to really do something special. But their upcoming schedule makes it look like it's possible.
These are their next 8 games (7 more would tie the record, 8 more would break it): Home vs Knicks, Home vs Mavs, Home vs Mavs, Away @ Nuggets, Home vs Pistons, Away @ Hawks, Away @ Hornets, and Away @ Pacers.
It feels like Utah will continue to be favored in most of those games. 6 of the next 8 are almost a guarantee that they will be favorites, other than @ Denver and @ Indiana.
This team seems to have a chip on their shoulder after losing to the Nuggets in a wild playoff series last year, and from receiving blatant disrespect from the media and ex-players. Donovan Mitchell and Rudy Gobert especially continue to be hated on, especially by one prominent big fella. (video via Bleacher Report)

Whether the Jazz are just a good team having a hot streak or this has spotlight is adding fuel to the fire, they are a force to be reckoned with right now. The rest of the NBA should watch out.
