No, the Saints' LSU draft picks, or lack there of, have almost no affect on the overall percentages. I will repost these numbers ...

1.) There are 778 colleges and universities in the United States with football programs according to footballfoundation.org as of June 28, 2018.

2.) Over the past twenty years those 778 sources have provided approximately 5,120 players to the NFL via the draft (20 years times 256 players).

3.) Over the past twenty years there have been 120 LSU players drafted. That comes out to an average of six LSU players drafted per year.

4.) In those last twenty years 2.3% of the players drafted league wide have been from LSU.

5.) Over the last twenty years the Saints have drafted approximately 140 players.

6.) Over the last twenty years the Saints have drafted three LSU players.

7.) Over the last twenty years 2.14% of the players the Saints have drafted have been from LSU. That's pretty much the league average. That means they are likely right about the median as far as drafting LSU players compared to the rest of the league. Half the teams have probably drafted more LSU players and half the teams have probably drafted less.

So, removing the Saints numbers from the overall league wide numbers we will recalculate.

Players drafted past twenty years minus Saints draftees: 5120 - 140 = 4980

LSU players drafted last twenty years minus Saints draftees: 120 - 3 = 117

Percentage of LSU players drafted overall with the Saints not included: 117/4980 = 2.349%

Your statement: "in fact, if you did the gymnastic scoring thing, and took the Saints out of it, that number would double..."

Oh, my! It looks like you were wrong!
