Ravens WR Lee Evans, heralded as a vital acquisition for Baltimore, has shown glimpses of his field-stretching ability early this season, such as on a 32-yard reception at Tennessee in Week Two. However, he has been bothered by an ankie injury early in the campaign. Evans caught only two passes in Baltimore's first two games (on nine targets) and his status for the Week Three game at St. Louis is in question after he didn't practice on Wednesday, Thursday or Friday. At his best, Evans' speed can "back people off," a veteran defensive NFL assistant told PFW, thereby making it more difficult to stack the line of scrimmage to stop RB Ray Rice. "They need that," the assistant said of the Ravens. The club's other true potential vertical threat, rookie Torrey Smith, is a work in progress. "He's really a great practice player, his preparation is good, he's growing," Ravens offensive coordinator Cam Cameron said of Smith this week.
