"I've seen a lot," Palmer said. "I've seen and played with a lot of suspensions and dealt with that and the injury thing."
When Palmer was the Cincinnati Bengals' quarterback, he had to overcome and eight-game suspension for receiver Chris Henry in 2007.
In Alexander's first six seasons, all with Washington, he had six teammates suspended.
"I've been around the league for a long time and being in Washington, it's always a circus so I'm kinda used to certain mishaps in a football organization," Alexander said. "Nothing can surprise me, I guess, at this point in my career."
Palmer has seen the ugly side of suspensions, but he's also seen how they can help a team. It helps teams become closer and stronger, he said.
"They make young guys have to mature faster," Palmer said.
"You do everything you can to bring the young guys around. These young guys that now are probably sitting back (thinking) it's a nice year for me to learn, but now it's a chance for a young guy who has to play and that's always a good thing. That's a good thing for that group of linebackers."
