As far as Ravens general manager Ozzie Newsome is concerned, the ball is in the court of offensive tackle Bryant McKinnie whether the former Pro Bowl blocker returns.
McKinnie is an unrestricted free agent who battled conditioning and weight issues and didn't regain his starting job at left tackle until he lobbied coach John Harbaugh, and left guard Jah Reid suffered a season-ending toe injury.
"BMac is a free agent, I think the way he played down the stretch against [Indianapolis Colts outside linebacker Dwight] Freeney, against [Denver Broncos outside linebacker Elvis] Dumervil, against [San Francisco 49ers outside linebacker] Aldon Smith, I think it makes a statement for him," Newsome said. "I think he has a decision to make as to whether he wants to come back and play here.
The Ravens reconfigured their offensive line for the playoffs and installed McKinnie at left tackle, shifted Michael Oher to right tackle and shifted rookie Kelechi Osemele from right tackle to left guard. They allowed just six sacks in four playoff victories.
"I think the thing we found out this season is we have probably about eight or nine offensive linemen with starter potential that were able to go and play very good football for us," Newsome said. "You saw that we've got good depth. But I think we like our young guys. I think Juan Castillo is going to be a great addition to our staff. He's known for helping and developing young players.
"I feel good about our offensive line. You said left tackle. Von Miller plays on the left side and he has to go up against the right tackle. So right now it's not a left tackle, right tackle thing. You have to have the ability to hold up on the left side or the right side."
