I am not a PFF apologist, but I have looked at their grades for a long time and I think most of the criticism misses the mark. Generally people do not understand how these are graded or what is and is not accounted for. The real friction is in the scaling and conversion, not the concept. The bigger issue is people throw out all the good because of one outlier that looks off. Every grading system has flaws and outliers. That does not discredit the whole thing. I thought the Bears offense was outstanding and Caleb's grade was low relative to where PFF had him. But there were also plays where he made a poor decision that turned into a good result. The downfield ball to Odunze is the perfect example. Odunze was wide open with no defender within 15 yards for a couple seconds. By the time the throw actually came out, he was covered, and he made a great contested catch. To the average viewer that is a great play made by the QB. In reality that is Odunze bailing out the throw. And I think that this is the part people tend to miss. Not grading the result is the entire point. It is not a flaw. The result is not always what the QB controlled. The way I approach betting this sport is you leave the ego aside and process as much information as possible. Some people are just threatened by spreadsheets. PFF is better at some positions than others and it is not perfect, but the discourse is always one person mad about one grade, used to torch the entire system. I think that's lazy. I think it's more important to understand the limitations and work from there.
