Quote:Well, [Posluszny] has a really good understanding of the defense and his pass coverage, I know, when you look at some issues that showed up a year, two years ago... they're not becoming issues anymore for us.  He has a really good understanding of the scheme.  If there's this speed thing that you're talking about, it's that experience and that wisdom of playing in the package that really helps him. A guy like Myles Jack has speed. No one disputes that.  And we're trying to speed him up as much as possible to get him out on the field because, boy, it's hard to defend that....  Hopefully [Jack] gets some reps this week.  If not, then if something should happen at either position then he's the next guy.
