SANTA CLARA, Calif. -- San Francisco 49ers coach Jim Harbaugh doesn't live under a rock, so he's fully aware of the performance-enhancing drug cloud hovering over his team's top rival.
The Seattle Seahawks have had five PED-related suspensions since 2011, tops in the NFL, and Harbaugh has taken notice.
"If you cheat to win, then you've already lost, according to Bo Schembechler," said Harbaugh, quoting his college coach.
For Harbaugh, it's a black-and-white issue.
"It has no place in an athlete's body. Play by the rules," he said. "You want to be above reproach, especially when you're good, because you don't want people to come back and say, 'They're winning because they're cheating.'"
San Francisco isn't without a link to PEDs though, as former linebacker Larry Grant, currently a free agent, faces a four-game suspension before he would be eligible to play.
"I've heard this thrown out or that, but that's usually the agent or the players themselves saying it's, for example, Adderall," Harbaugh said. "But the NFL doesn't release what it actually is, so you have no idea.
"You're taking somebody at their word that I don't know if you can take them at their word, understanding the circumstances."
Seahawks cornerback Richard Sherman, who played for Harbaugh at Stanford, tested positive last season but had his suspension overturned after successfully arguing the testing process was flawed.
--Cornerback Nnamdi Asomugah is still learning defensive coordinator Vic Fangio's system and his role isn't clear, but that hasn't stopped him from taking on a leadership role.
"I've always been a leader throughout my career. I would definitely say that," Asomugah said. "The guys have looked at me in that way already and I'm just stepping foot here for a couple months."
--A 63-year-old mechanic died at the construction site of Levi's Stadium, where the 49ers are set to begin play in the 2014 season.
The organization released the following statement:
"The 49ers organization was deeply saddened to learn this morning of the news at the construction site. Our thoughts and prayers are with the family, friends and co-workers affected by this tragedy. The 49ers family has lost a teammate today."
