re: There are 927 total votes for Heisman. Let’s see who gets the closest

In case anyone wants to know what Joe needs to break the various voting records:

tl;dr:
Joe beats every relevant record for Heisman winners with 856 first place votes and at least an additional 27 votes of either 2nd or 3rd in any proportion.

Details:

1st place votes - 856 would beat OJ Simpson's total, although Juice's class had almost 300 more voters.

% Possible points - 91.7% (2551). Out of 2,781 possible points, he could get this with 851 1st place votes, although he wouldn't need that many as 2nd and 3rd place votes would add to the point total as well.

Most ballots named (% of total ballots) - 95.2% or 883. He needs fewer than 44 slap dicks to leave him off their top 3 to get this one.

Margin of victory is too varied to predict and isn't relevant due to the massive number of voters for OJ's year.
