In the spring, there's not too much for football heads to obsess over and argue about--so we make do with what we have. In the name of starting a few Federal Hill bar arguments, here's my guess at the Ravens' starting offensive lineup, complete with odds for each candidate. Favorites first, then progressing towards the long-shots.

QB

Kyle Boller (3-2)
Troy Smith (3-1)
Joe Flacco (8-1)

Boller gets the nod, more by default than anything else. Smith didn't display great vision in the two games he played, and Flacco's going to need some time to adjust to playing against real defenses.

RB

Willis McGahee (1-5)
Ray Rice (6-1)
P.J. Daniels (7-1)
Cory Ross (7-1)

Coming off a Pro Bowl Alternate 2007 season, unless McGahee blows out both knees, breaks his femur in six places and gets paralyzed from the waist down, he'll start. Rice will compete to spell him with the rarely-used Daniels and Ross.

FB

Le'Ron McClain (1-2)
Justin Green (4-1)
Haloti Ngata (50-1)

McClain was mostly solid, if unspectacular, his rookie year. He's not a very natural runner or receiver, but neither is backup Green. Defensive end Ngata has gotten a few reps in practice, and even though the former high-school rugger fumbled the snap... good God, I'd love to see those 345lbs. heading for the goal line with a head of steam.

WR*

Derrick Mason (1-2)
Mark Clayton (1-2)
Demetrius Williams (3-1)
Yamon Figurs (12-1)
Justin Harper (40-1)
Matt Willis (50-1)
Kerry Reed (50-1)

Derrick Mason is on the decline and Mark Clayton is looking like a pretty major flop, but Williams hasn't done much to inspire confidence either. At this point, Figurs looks less Devin Hester and more Ted Ginn, Jr. *We're calling the top two WR starters.

TE

Todd Heap (1-3)
Daniel Wilcox (4-1)
Lee Vickers (7-1)
Field (30-1)

Heap isn't as serious an injury risk as the hand-wringers have made him out to be. With any luck, he'll be more than a short-yardage bailout option this year. Ideally, new offensive coordinator Cam Cameron will be able to use move Heap around, like Indianapolis does with do-everything tight end Dallas Clark. But I'm not holding my breath, for reasons that become clear with the next five positions...

LT

Adam Terry (2-1)
Jared Gaither (4-1)
Marshal Yanda (5-1)
Jonathan Ogden (15-1)

Man-mountain Ogden won't be around to keep the quarterback's uniform clean...probably. Adam Terry is the most likely to get the blind-side slot again, though sophomores Yanda and Gaither may get a look.

LG

Chris Brown (3-2)
Ben Grubbs (2-1)
Marshal Yanda (5-1)

Chris Brown hits like a runaway freight train on running plays, and the Ravens are going to need to be able to run the ball.

C

Chris Chester (3-1)
Ben Grubbs (4-1)
Marshal Yanda (7-1)

Chester's not the best lineman the Ravens have, but at this point, he can make better blocking calls than either Grubbs or Yanda. However, it sounds like Yanda's getting reps at center, as well as guard.

RG

Ben Grubbs (2-1)
Marshal Yanda (5-1)
Mike Kracalik (9-1)

With Brown and Chester holding down the LG and C positions, 2007 first-round pick Grubbs will probably reprise his starting role at RG. Offensive line depth will be an issue for the Ravens again this year, as they have relatively few proven players.

RT

Marshal Yanda (2-1)
Adam Terry (5-1)
Mike Kracalik (15-1)

If the Ravens go with this offensive line, they'll be a pretty decent run-blocking bunch, but they'll have a hell of a time keeping a quarterback ambulatory and conscious.

Naturally, since gambling is illegal, I won't be taking bets on any of these (though if you really think Justin Harper has a chance of starting this year, let's talk).
