Microsoft Cortana went 10-4 in Week 7 - here's who it thinks will win in Week 8

Microsoft Cortana - the virtual assistant that picks the outright winner of every NFL game on Bing - had a nice Week 7, going 10-4. The successful picks pushed Cortana's record to 67-38 on the season.

Cortana's four misses all came in upsets. It favored the Bills over the Jaguars in London, and the Steelers over the Chiefs in Kansas City. It also missed on two home teams - the Colts and the Chargers.

At 63.8% correct on outright picks (not Vegas point spreads), Cortana still trails 538's Elo model, which has a record of 73-32 (69%). Elo went 9-4 last week, and pegged the Vikings versus Lions at 50/50 odds. According to NFL Pick Watch, Gordon McGuiness of Pro Football Talk is leading the field with 73% correct.

This week, Cortana mostly likes home teams. Notably, it thinks the Patriots shouldn't have too much trouble in Foxborough on Thursday night against the Dolphins, and believes the Saints will make it three straight home wins by beating the Giants in New Orleans. Cortana's road favorites - the Vikings, Cardinals, Bengals, and Seahawks - are all also favored by Las Vegas.

The best game of the week is also the one in which Cortana and Las Vegas disagree. Sunday night, Aaron Rodgers and the 6-0 Packers face off against the 6-0 Broncos in Denver. Cortana gives the Broncos a slight 53% edge, while Vegas likes the Packers by three points on the road.

As always, you can find Cortana's picks by searching "NFL predictions" on Bing, and you can read about the decisions behind each pick from the Bing Predicts team on Bing Blogs.
