As everyone else says, it depends on the cost. But I don't see the Packers doing much more...
Maybe sign a cheap Center, who can start if needed, to free up Jenkins if we need to move him around.
I still wouldn't mind resigning Lane Taylor, I'll take the gamble it won't happen three times in a row and sign him to a minimum deal (note, I don't think it will happen three times in a row unless the Packers sign him, then I will, but still minimum would be worth the risk).
What the other guys said about the DL Casey.
ILB depends on what we're planning to run, if Tampa 2, then yeah, we need a coverage ILB, if not, we might go with what we have.
Ervin is reportedly visiting the Bills right now. Zero, are you asking about him selling merchandise? Or the possiblity of Patterson in GB? I've said I'd like both Ervin and Patterson... I don't think Patterson is a punt returner, but I think he has more power can be used more like a TB and has deep speed, where we can run both MVS and Patterson deep, can't double both of them. I think the Packers want more speed... and Patterson should be able to do the sweep.
