Does the Pack have sufficient LB depth?

Packrphan seems to have his pulse on the team's personnel and the info. that is available about them. So, I am wondering what is the strength of the LB crew. I haven't seen or heard anything lately. Last I heard is that Hodge is not performing. First team seems solid (Popinga?), but I for one will be watching for how the second and third-string LB's do. I see that Trotter was let go by Philly yesterday. Would he be a reasonable pickup for depth, or perhaps he sees himself as a starter only? Anyway, I would be interested in seeing and hearing some confidence building material on the Pack's LB depth. Anyone?
