You know, pre-2019 saying “LSU is a place to develop quarterbacks” wasn’t that crazy historically speaking, at least.
You of course had JaMarcus Russell go first overall in the 2007 NFL Draft; Matt Mauck (2004), Matt Flynn (2008) and Danny Etling (2018) all went in the seventh round of their respective drafts, while Zach Mettenberger went in the sixth and likely would have gone higher had it not been for his ACL tear at the end of the 2013 season.
If you wanna go back to drafts pre-2000, well LSU’s pretty well represented there, too.
