Commissioner Goodell has ordered the owners of all 32 NFL teams to make sure their clubs are not offering bounties like the New Orleans Saints did from 2009-11.

Goodell's memo instructs each team's principal owner and head coach to certify in writing by March 30th that no pay-for-performance system exists.

Goodell says that bounty programs are “incompatible with our efforts to promote sportsmanship, fair play, and player safety."
