Chances that the Ravens draft an offensive lineman in first three rounds: High. The Ravens' biggest need probably is at right tackle, where Wagner, a fifth-round pick last year who played sparingly in his rookie season, currently tops the depth chart. His top competition for the job is Reid, a former third-round pick who has yet to establish himself as a capable starter. The Ravens, who would prefer keeping Osemele at left guard, need another option at right tackle. However, some draft pundits have predicted as many as five tackles could go before the Ravens are on the clock at 17. That could cause them to wait a round or two before grabbing one. The Ravens also need more depth at guard, but that's probably something they'll look for on day three.
