The have some , but help may be on the way.The Ravens lost some key starters from the offensive line this offseason, as they traded right tackle Morgan Moses and lost guards Kevin Zeitler and John Simpson in free agency.Now OTAs Alex Ovechkin Jersey , which wrap on Friday and lead into minicamp next week, are a time for the Ravens to test out who might be able to fill those holes.The good news: Ravens head coach John Harbaugh says there are multiple candidates, and all of them look worthy."I've seen a lot of big guys that can move and work hard, pick things up quickly, Harbaugh told reporters. "The nice thing is nobody's going out there that you say, 'I don't think hes going to be able to do it.' So far, every single guy looks like he could be the starter. Now, we get into pads. We get into preseason games, let the guys compete against one another and see who wins the jobs. But, all of them are still in contention at this point, which is very good."Of course, voluntary OTAs are a different beast than training camp and preseason. As , sixth-round rookie Sala Aumavae-Laulu looked impre sive in last year's minicamp, but he struggled Brooks Orpik Jersey in preseason and didn't play in the regular season.That same situation could play out this year with a number of players competing for the open spots and no clear front-runners yet.One name to watch, however, is one of the Ravens' biggest X factors of the offseason: Andrew Vorhees.The second-year guard was expected to be a Day 2 draft pick last year, but fell to the seventh round because of a knee injury. Vorhees mi sed his entire rookie season rehabbing, but he is now healthy and practicing with the team. If Vorhees can live up the potential he showed in college, he could be a huge addition to the shaky front line.
