His full quote makes a lot of sense. He didn't blame the QB, but he's right that coaches should be teaching QBs different tactics so this doesn't happen as much.
"You've gotta learn how to protect yourself," said Ryan. "And I'm going to tell you right now, obviously it was a dirty hit, I am so sick and tired of seeing people teach, Hey, slide. When you're running out here, you slide. The (heck) you do! Not when you're going full speed down the field and the defender's coming full speed at you. You don't slide. I can see this happens over and over and over again. All you have to do is watch every Saturday, college football. Two to three of these happen every single week. I'm sick and tired of it. You are not protecting your quarterback when you teach them how to slide when it's not in the open field. Open field of course. That's great. Absolutely not here. If you want to get a concussion you slide like this when contact's coming."
