[QUOTE="slugboy, post: 621681, member: 282"] I don’t think you can add QBRs to get a combined QBR. I can’t see any other way three QBRs of 49, 9, and 5 combine to a better QBR of 63. Even averaging them wouldn’t be the right way to get a combined QBR, but it would be closer. TO, LJ, and JG didn’t get equal playing time, but 63/3 = 21 would be closer to the combined QBR for the game. EDIT: I used the calculator at [URL]https://www.pro-football-reference.com/about/qb-rating.htm[/URL] to get the combined QBR. It was [b][u]45.14[/u][/b]. Graham’s stats really boosted the overall, but TO’s and LJ’s stats brought it down a bit. 63 is nearly respectable. 5 and 9 aren’t. [URL]https://slate.com/news-and-politics/2001/08/how-does-the-nfl-s-quarterback-rating-system-work.html[/URL] 1. Completion percentage: Subtract 30 from the percentage of passes that are thrown for completions, then multiply by .05. 2. Yards per attempt: Subtract yards per passing attempt by three, then multiply by .25. 3. Touchdown percentage: Multiply the percentage of touchdown passes per passing attempt by .2. 4. Interception percentage: Multiply the percentage of interceptions per passing attempt by .25, then subtract that number from 2.375. The scores for each category are added together. That sum is divided by six and multiplied by 100, which converts it into a rating on a scale from zero to 158.3. A putatively average QB would receive a rating of 66.7 (1 + 1 + 1 + 1 = 4, and 4/6 * 100 = 66.7). We could do it by putting in the aggregate stats. Sent from my iPad using Tapatalk [/QUOTE]
