"You've got to just get ready for the system. It's Norv Turner's system. When it's all said and done, it's still his system," the Ravens defensive coordinator said. "I don't think it will be much different than what he did with Weeden. … Willis is a lot like Richardson in a way. This isn't a bounce-out, try-to-get-to-the-edge runner. This is a downhill thumper, which is what Richardson was. So I don't see a great deal of difference. It's different names, but I just don't see a whole lot of difference in this offense."
