Senor,
As a lifelong Seahawks fan, let me say that Seneca Wallace is not a good QB. He's an excellent athlete, no doubt, but he's not a good QB. I don't know if people are just impressed with the Hawks win last week against a horrid SF team, or if they are remembering Wallace from his Iowa State days (where rushing yards matter moreso than in the NFL).
Just my opinion obviously, but I think it speaks volumes that the Hawks coaching staff have been trying to move him to WR/kick returner for quite a while now. The only reason they haven't is because they haven't gotten a good backup for Hasselbeck. I think they thought Frye might be the answer. Obviously that didn't work out.
GL with your plays...
