You say you want Richards but not others because they're too old and worthless in the same post. If you want Richards back at any price you're ok with old and useless.
I want Richards if Holland doesn't manage to trade for a Centerman. And I'd want him because he played very well lately plus he knows the players and system already. Richards is an excellent teamguy and we need a strong 2nd/3rd Center to shoulder a little bit for Z. If Z has to do all the work in the defensive zone he's not gonna play a good season.
