Plug in a few numbers. Press the Calculate button. And just like that, a number pops out, displaying your quarterback’s performance. 31.4? He had a bad day. 128.7? He put up a show. Amazing isn’t it?I would like to say that the NFL Quarterback Rating Formula precisely measures quarterback performance. But it doesn’t. The problem is two-fold. First, all variables must be included to produce a precise rating. Second, these variables need to be perfectly quantified. Presently the formula includes attempts, completions, passing yards, passing touchdowns, and interceptions as metrics for determining a quarterback’s rating. However, there is no conclusive statement that can quantify the qualitative. For example, no one can state with conviction that passing yards are 32% more relevant than interception rate. In addition, the formula also lacks sacks, composure, and fumbles, among many other variables, that are crucial in order to determine quarterback performance.
