Era-Adjusted TD/INT Ratios: Worst Seasons And Career List

by Chase Stuart on August 16, 2016

Yesterday, I looked at the best seasons in TD/INT Ratios after adjusting for era. Today? The worst, using the same formula.

Only one quarterback has ever qualified for the league passing crown but also failed to throw a touchdown: Bobby Hoying in 1998. That season is the only thing keeping rookie Ryan Leaf from the bottom of this table.

Here’s how to read it, using Leaf as an example. Leaf threw 2 TDs and 15 INTs in 1998, a 0.13 TD/INT Ratio on 245 passes. Leaf averaged 0.82 TD passes per 100 attempts – a laughably low number that is one of just four below 1.00 seasons — when the league average was 4.23. As a result, meaning he was at just 19% of league average. He threw 6.12 interceptions per 100 attempts, when the league average was 3.27, so he was at just 53% of league average. Multiply those two numbers (19%, 53%) and Leaf has a value of just 0.10, second worst in NFL history. That said, Hoying was so bad he would have needed two touchdown throws to move out of the cellar:

Finally, we can also create a career list, although I’d be a little careful about this. For starters, this only includes qualifying seasons, so we are not looking at full career totals. And players who are still in their prime get a boost, as we are not yet including their down seasons. And this method (rather than a 100-95-90 method) gives no extra credit to top seasons, the way we typically do when we think about quarterbacks.

That said, here’s the list of the 150 quarterbacks with the most attempts. Note that this is attempt-weighted:
