The Baltimore Ravens might be facing bad news about fixing their biggest weakness

Two weeks of training camp doesn't seem to have given the Baltimore Ravens any clear answers on the offensive line.

Offensive line has arguably been the Ravens' biggest question mark after losing three starters during the offseason . The Ravens didn't make any major moves to replace those veterans.

Now, training camp is essentially serving as open auditions for both starting guard jobs as well as right tackle.

So far, only Andrew Vorhees, essentially a red-shirt rookie, seems to have made a positive impression at left guard .

The Ravens are rotating through players at right guard and right tackle, and it doesn't sound as if anyone has stood out as the clear-cut starter.

There may be signs already that the lack of proven depth is a problem. Ravens head coach John Harbaugh praised linebacker Odafe Oweh's performance during training camp and said Oweh has been in the backfield almost every play . That's not a positive reflection of the offensive line.

This comes as one NFL analyst predicted the Ravens' O-line to be the worst in football .

Furthermore, The Athletic's Jeff Zrebiec writes that although the Ravens will look for players to add in free agency, fans shouldn't expect a savior.

Zrebiec writes:

"The Ravens, though, will probably have to find the solutions internally. The demand for quality linemen far exceeds the supply. The free-agent market isn’t exactly overflowing with healthy and starting-caliber guards and tackles this close to the season. Anybody Baltimore adds would probably be more a depth piece than a bona fide starter. Still, that won’t stop general manager Eric DeCosta and company from looking around. Thirty-one other teams will be doing the same."

Zrebiec had previously written that he expected the Ravens to make some late signings to add to training camp, as they have done in past years. The Ravens did just that, adding safety Eddie Jackson and re-signing defensive back Daryl Worley. It may be telling that the Ravens haven't added any offensive linemen yet.

Of course, it's also possible that the Ravens wanted to see their offensive line in action before making any moves. Had some of their young players stepped up and looked ready to start, a veteran addition right now might have been unnecessary.

Still, as Zrebiec notes, it seems unlikely that Baltimore can find anyone at this stage who can come in and fortify the offensive line. Such an addition might be an average-at-best player.

It's worth noting that the offensive line will become easier to judge once the games begin. Although players may hit in training camp, it's not the same as full-speed snaps during real games. So, preseason could change the perception of the offensive line — but right now it doesn't look good.
