The Seattle Seahawks have accounted for 10 percent of the NFL's 50 PED suspensions since 2010.
Bruce Irvin was the most recent member of the Seahawks to receive a suspension.
Kam Chancellor and other veteran Seahawks called a team meeting to discuss the issue.
"We had our meeting. The vets put a meeting together to talk to the guys about not making the same mistakes over and over," Chancellor said. "You know, we gotta grow up and move past that. So that's pretty much the message right now -- growing up and not making the same mistakes over and over."
