I don't believe this one bit. Lombardi gave Richards a chance by not buying him out during the offseason. It'd make no sense to turn around and move him a few months into the season. There will be a team that takes Richards, whether it be Edmonton or whoever else.
Richards won't be a King next season, if he isn't moved by the deadline he will be moved in the offseason.
Buying him out now will handicap the Kings for what, the next 5 years? It wouldn't be worth it. He will be traded even if it's just for a pick.
We're past half-way through the season and Richards hasn't shown any sign that he's waking up. It's the same Richards. Time to cut the dingleberry loose.
