Weddle got to see Lamar Jackson in action over the second half of last season, and watched the transformation of the Ravens' offense first-hand. Baltimore has changed a lot since Offensive Coordinator Greg Roman and his staff rebuilt the offense this offseason, but the basic principles are the same.

"I don't know how you can counteract his intelligence other than just know that he kind of knows, I guess," Harbaugh said. "He knows how to match routes. He'll recognize formations. He'll get his guys lined up, and he'll be in the right spots."

It's still a question of how much Weddle's understanding of the Ravens offense will impact Monday night's game.

"Obviously the tape is out there of every single game we've played. It's not a secret or mystery of what we're doing," guard Marshal Yanda said. "Yeah, he might have more of a grasp on it, but still at the end of the day, it's executing football, it's blocking people, it's running crisp routes, it's making good throws and all that stuff."

Yanda stressed how much respect he has for Weddle, who was part of the team's leadership council and workout warriors. Clark talked about how much he learned just from studying how Weddle went about his business. Weddle's enthusiasm was a catalyst for Baltimore the past few years, and he's had the same influence on the Rams.

Weddle has started every game this season and made 72 tackles through 10 games, which is already more than he had each of the past two years. He has three pass deflections but no interceptions so far.
