It is not about giving up on Randall so much as not counting on him putting it together. I don't remember Randall being injured, but his failings did not look like someone covering for an injury (Rollins' problems did look that way), they looked like a guy who did not know how to play CB, did not try to learn the CB position, and tried to let his athleticism cover for everything. He was out of position and screwing up technique. I'm not saying those things are not fixable, and I don't think McGinn was either, just that you can't count on them ever getting fixed. At this point the Packers have to prepare like they won't get fixed if they want the best shot at a Super Bowl.
