These plays are hard to forget and make us sit in awe of a quarterback’s poise and talent – as we should. Those plays are massively important and often determine the outcome a game. However, it is important that we don’t confuse plays that explain what happened with performance that is likely to happen again. When you win the lottery you don’t immediately buy more lottery tickets (you go straight to Vegas).
Pressured plays by nature are diverse. You’d be hard-pressed to find two plays under pressure that look exactly alike. To pile on, pressure occurs on just about 35.0 percent of dropbacks making the sample size of pressured plays much smaller than its ‘less-sexy’ counterpart, the clean pocket.
This begs the question, if we want to predict the future, should we put more stock in how a quarterback plays under pressure or from a clean pocket.

Traditional data points: under pressure vs kept clean
To get our bearings, we’ll start by looking at a couple of metrics that everyone is very familiar with: completion percentage, yards per attempt and passer rating. We considered all quarterback seasons with more than…
