It's not that cut and dry, but that's definitely part of the mind game behind it though. People get so complacent because they don't know the first thing about stopping the Bobcats (why would they? they're never on T.V., and nobody ever uses them...)
As for Miami, I found that the Wizards are a great team to counter the constant driving of Lebron and Co. They got the mismatch at both positions that are good to play D on, and Wall blows past anybody and can finish in traffic.
