Matthew Stafford has had interceptions returned for touchdowns in three straight games. If he throws a Pick Six against Jacksonville this week, he'll tie another Matt, Matt Schaub, for most games in a row with such a miscue in NFL history. It's a pairing he'd no doubt like to avoid.

Whether he does or not, Stafford is already high on the list in terms of frequency of throwing Pick Sixes. Among quarterbacks who have thrown at least 10 in NFL history (since the league started tracking them), only four have thrown them with greater frequency (on a per-game basis) than Stafford. There's a Lions connection (Joey Harrington is one of the four.

In the table, generated from pro-football-reference, players are sorted by per-game frequency of throwing Pick Sixes. Stafford has thrown one in nearly 15 percent of his games, more frequently than anyone this century besides Harrington and Blake Bortles. Active players are italicized.
