If defense wins championships, then why are most of the mock drafters going offense so far on our Windy City Gridiron Member Mock Draft? That's a rhetorical question. Picking at #12, for the Seattle Seahawks is myronaiii so without any further adieu let's get to his pick and his "brief" explanation.

And with the 12th pick in the WCG Mock Draft, the Seattle Seahawks select...

David DeCastro, Guard, Stanford

myronaiii: Like most teams, Seattle has multiple holes to fill (giggity). They are currently short two starting linebackers, they needed help on the defensive line, they started Tarvaris Jackson, and their Oline was in shambles. I could throw WR in here as well, but I've got to think Rice and Williams can stay healthy for an entire season at some point in their carriers; plus, they have young WRs that are helping out (see Doug Baldwin).

Although most mocks show them going DE, and I almost chose Ingram here, I couldn't stop staring at their offensive line. They had multiple linemen go on IR last year. Some of them are gone to free agency, including a starting guard, and some of them are still recovering from injury. Additionally, I dare you to go look at their bios. At least 2, if not 3, of their starting OL were on practice teams within the last couple years. They are serviceable, but not elite. And that is were DeCastro comes in. This guy can push DT's back into linebackers. He's strong, smart, and has an aggressive motor. I read some sports writer mention that he saw DeCastro jogging....AFTER HIS PRO DAY.

Seattle just signed what they hope will be their franchise QB (I know, I know...there's a "competition" between Flynn and Jackson, but come on). They also locked down Lynch. They need an elite player on their offensive line. They already have an at least average center and one good guard. I think with DeCastro, who has the skills to be a top Guard in the league, they will have the ability to pass more often because a pocket will be created, and they'll have a better running game with DeCastro making holes or pulling to provide relieve on outside runs.

Finally, regarding this pick, one of the tipping point factors was this team signing Omiyale. If you read their website about the signing, it repeatedly states the Bears released him solely because of salary cap issues. It said nothing about his stats and ratings. If you are signing Omiyale to come on to your offensive line, that position is obviously a need.

Note: In real life, I would've traded down to around 19-21 and grabbed a DE there and hopefully add an additional second rounder. Also, I think that Seattle's LB concerns can still be addressed in FA, and a good LB can be had in rounds 2-4. Depth at DE is why I had to pass up that position. At pick #12, I feel more confident that DeCastro will be a Pro Bowler than I am the DEs on the board. Plus, regarding DE, Seattle just signed two starting DEs.

On the clock, picking for the Cardinals: el_padrino or Cutler6...
