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 Buffalo Bills over the Jacksonville Jaguars in London, and the Pittsburgh Steelers over the Kansas City Chiefs in Kansas City. It also missed on two home teams — the Indianapolis Colts and the San Diego Chargers.

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

This week, Cortana mostly likes home teams. Notably, it thinks the New England Patriots shouldn't have too much trouble in Foxborough Thursday night against the Miami Dolphins, and believes the New Orleans Saints will make it three straight home wins by beating the New York Giants in New Orleans. Cortana's road favorites — the Vikings, Arizona Cardinals, Cincinnati Bengals, and Seattle Seahawks — are 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 Green Bay Packers face off against the 6-0 Denver 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.
