OWINGS MILLS, Md. (AP) — Ravens safety Matt Elam has plenty of words to describe wide receiver Calvin Johnson, the main object of focus for Baltimore's defensive backfield Monday night in Detroit.

Those words include "big, fast, athletic, unstoppable, freak."

Curiously, Elam went in another direction when asked how best to cover the 28-year-old Johnson, who's amassed a club-record 9,184 yards receiving and 67 touchdowns in less than seven years.

Elam said, "He's pretty old, so I don't know how physical he'll be. He's a big guy, but he's older."

Johnson is 28 and Elam, a rookie, is 22. The misinformed 5-foot-10 rookie can only hope he doesn't have to tackle the 6-foot-5 Johnson in the open field Monday night in a game both Baltimore (7-6) and Detroit (7-6) desperately need to win.
