I was once a hater.
After Derek Carr's rookie season, I questioned his future as a franchise quarterback at the NFL level. Based on the Net Expected Points (NEP) metric we use at numberFire, things weren't looking good. The probability of him becoming a significant signal-caller based on his rookie season numbers was small, as there's been a general correlation between first-year success within the metric and how those rookies go on to perform throughout their careers.
It was a look at probability more than anything else. But Derek Carr apparently doesn't care about probability, odds, or not being able to break the mold because his improvement year over year over year has been one of the craziest, best progressions we've ever seen at the quarterback position in league history.
