Even if Corey Graham has the athleticism and the talent to keep up with Wes Welker, the bigger concern becomes whether the Ravens will be able to adapt on the fly and get everybody in the right place against the league’s fastest offense without making mental mistakes. Peyton Manning only had a decent game throwing against the Ravens out of an occasional no-huddle last week, but that Denver offense doesn’t run the no-huddle in the same way that New England does. It had a devastating impact on the Texans, and it could end up being a difference-maker against Graham, Brown, and even veterans like Ed Reed. All the talent in the world doesn’t matter if you’re not in the right place.
