Arizona Cardinals defensive lineman Darnell Dockett is participating in a chat at ESPN.com this afternoon, and just took a pretty good shot at Pittsburgh Steelers quarterback Ben Roethlisberger.

"Nick (NJ) Witch [sic] QB Do you have most trouble trying to sack and which QB is the easiest to sack?"

Darnell Dockett (2:42 PM) "The toughest QB to sack is Ben Roethlisberger. The easiest QB to sack is Ben Roethlisberger if you can catch him in a bathroom stall."

When asked if he expects to be fined for making that comment, Dockett replied "Why? What did I do? I'm just going by what I read. That's all."

It's worth noting that Dockett had three quarterback sacks in the Cardinals' 27-23 loss to Roethlisberger and the Steelers in Super Bowl XLIII. Dockett also had 2.5 sacks of Roethlisberger in Arizona's 21-14 win over the Steelers in 2007. With sacks of the 6-5, 250-pound Roethlisberger accounting for 5.5 of Dockett's 30 career regular and post-season sacks, it's easy to see why Dockett may feel he's the easiest to put on the ground.
