The final rosters for the upcoming NFL season haven't been
released yet, so these numbers are current as of the 2013 NFL
season. LSU, Miami (Florida), and USC are all three tied with 58
current NFL players.
I would say Purdue (Brees & Orton) for 2008. Otherwise
injuries changed things. Such as other notables USC (Cassell &
Palmer), and BC (Ryan & Hasselbeck).
