Pretty good week for the ol’ GRT Statsy Preview Machine. It went 27-18 (60%) overall, 12-5 (70.59%) in Category 2, and 7-4 (63.64%) in Category 3. For the season, the Machine is now 239-210 (53.23%) in Category 1, 92-74 (55.42%) in Category 2, and 47-37 (55.95%) in Category 3.
Of the seven “Category 4” games, one was postponed, and I excluded another because it wasn’t actually a Category 4 game. The others went 3-2 (60%), making the results for the five weeks we’ve been tracking them 14-3 (82.35%).
Using the same spreads as SP+, the Machine was also 27-18 (60%) overall for the week.
SP+ had a rough week, going 20-25 (44%) officially, using its own spreads. It happens. For the season, SP+ is 229-217-6 (51.3%). It did the same against our spreads this week and is now 246-203 (54.79%) for the season against the same Vegas opening spreads that we use.
Below are the GRT Statsy Preview Machine’s picks for Week 15 of the 2020 college football season. As always, if you’re wondering why we do this or what I mean when I refer to “confidence” and when I place game predictions into different categories, check out this post. Also, in case it’s not perfectly clear from the above results, spreads matter.
