The Ravens have acquired wide receiver Lee Evans from the Bills, according to a league source. Buffalo will receive a fourth-round pick from Baltimore. "It's not a whole lot I can focus on because I have no control," Evans said of rumors on Thursday. "My main goal is to do everything in my power to help this team win. That's what my focus is more so than anything." With two years left on his contract, Evans said he hadn't asked for a trade.
