For Lane's era = 49.6% completion percentage
For Sherman's = 61.9%

Thank you, John.
I remember the days when a 50% completion rate was considered "good."
Nowadays it's considered atrocious. How the game has changed...

Here are some interesting analytics

From 2011-2017 2.6% of the passes have been picked off

That's a pretty amazing statistical difference.

I bet it would be similarly different.

I can get that... but yes, completion percentage has skyrocketed...

There is a weird mathematical relationship between league completion percentage and league interception percentage that has held up throughout since 1933. If you take the end of the season passing stats for the league for each season (NFL, AFL or AAFC), and graph Y=C+2.3*I, where C is the league completion percentage and I is the league interception percentage for any given season, Y always stays in a range between .6 and .7, and has only been outside that range three times. In 85 percent of all seasons, C has remained between .63 and .68. As completion percentage increases by 2.3 percentage points, interception percentage has to decrease by one percentage point in order to keep it steady. I know this sounds strange, but if you check this out you will find this to be true.

Wow, that's really amazing!

Sherman's had a great career. But IMO to be a lock to be elected into the HoF, he'll need a few more stellar seasons, which he is very capable of. Looking at the stats above, I think he's just about there. I would vote for Sherman.
