Errors happen to the best of us. I work in a small shop, where staffers do it all, writing, copy editing, page design, web work, in one shift. Do we try our best? Yes. Do errors get through, because everyone is busy with their own work and doesn't have time on deadline to proof a page as well as they want to? Yes.
But when you're Sports Illustrated, a publication that comes out once a week, with the resources that they have, mistakes should be extremely rare. How many times on this board have people pointed out mistakes this magazine has made? How many times do people write letters to the editor of SI pointing out errors, only to see in italics, the words "SI regrets the error".
This error could have been rectified with one brief look at the Seahawks' roster. "Who wears No. 3? It's Josh Brown." Yes, Brown and Hasselbeck do bear a resemblance. But you would think that somebody would have taken the time to check that ID one more time.
