The Dwight Howard trade was an asteroid hit that rocked this sport. It changes the calculus of multiple teams, as suddenly their rosters aren't suitable for what the league now is.
In the meantime, Dwight Howard could be a disaster in Los Angeles. It's not out of the realm of possibility, though I believe he'll do fine in La La Land. If Howard does run into issues as a Laker, then he too will go on the trading block.
