They aren't already? Sure could have fooled me the last 2 weeks.
Seriously though, there's no reason to even consider tanking. If we continue to play as poorly as we have been, we won't be winning many more games, whether we're trying or not. Losing and getting a higher pick will take care of itself if we continue to suck.
If we don't, then the flip side of it is we play in a totally winnable division and if we get hot we could be asking in 2 months if we're a team that could make a run in the playoffs, regardless of what happened mid season this year. So much changes over the course of an NFL season.
So as always, we should wait and see what happens. You only get 16 guaranteed Packer games per year, I'd never want to throw away one, even if they haven't been much fun to watch lately.
