- After a slow start to the season, Cortana and Elo have been on fire in recent weeks.
- The two models we're tracking have correctly picked 64% of the games this season.
- Both models had a bad Week 14, but are looking to rebound in Week 15.
The NFL season is now in Week 15, and the two computer models finally had a bad week after a solid two month run.
We took a look at two popular systems used to pick NFL games: Cortana, Microsoft's digital assistant, and Elo, the modeling system used by Nate Silver's FiveThirtyEight.
In both cases, the computers are picking outright winners and not against the spread. However, each gives a likelihood of a team's winning, which, in theory, could help measure the strength of certain lines.
Both models have been on fire in recent weeks, but finally came back down to Earth in Week 14. Cortana went a disappointing 8-8 last week after going 77-24 over the previous seven weeks. Cortana still holds the overall lead, with a 136-72 (65%) record on the season. Elo was a game worse in Week 14, going 7-9, and is now 130-78 (63%) overall.
Here are the picks for Week 15, with each model's percent chance of winning in parentheses. Games in bold are where the two models disagree on who has the best chance to win. Point spreads are just for reference, via Vegas Insider as of Thursday morning.
