The NFL's accusation that the New Orleans Saints offered "bounty" payments to players for injuring opponents raises a few questions: How many potential payments are we talking about? Which Saints players were the biggest beneficiaries? And how many times did the Saints actually knock the tuna salad out of somebody?

A Wall Street Journal review of every regular- and postseason Saints game since 2009 makes clear what the NFL report didn't: Seldom did a Saints-inflicted injury force an opponent to leave the field.

In 48 regular-season and six postseason games, such incidents occurred only 18 times. The Saints player involved in the largest number of those cases was safety Roman Harper. That number was four.

An NFL official said Monday that league investigators spoke with Saints former defensive coordinator Gregg Williams, who has acknowledged playing a role in the bounty system. The league has yet to levy penalties and an official said it must discuss the matter with the players union before doing so.
