While the Pistons aren't even close to being a legit team right now, the departure of Lebron from the Central division can't do anything, but help us. It turns a Cleveland Cavs team from a 50+ win team into a 20-30 win team at best overnight. This opens up a path for prime playoff seeding in the next 5 or so years for anyone left behind.
Division winners in each NBA conference get the top 3 seeds on their side of the bracket. This means that even if you were the 8th best team in the playoffs, even though you won your division you are at worst a 3 seed. More home games is your reward for playing in a terrible division.
While the Bulls are probably in the best shape of us all in this horrid division, things change fast in the NBA and the lack of Lebron can only help us reach the top much sooner. Of course the need for a hair loss cure worrying about actually trying to knock off a team that has Lebron, DWade, and Chris Bosh to actually win anything is still a long ways off.
Hey, we knocked off the 2004 Lakers so it isn't unheard of for a dream team to go down to someone nobody expects. I'm sure luck will come into play at some point with injuries from this big 3 eventually and give someone else a shot. Maybe they implode like the Lakers did too and can't play together?
Anyways, SEE YA LEBRON!
