Let’s compare the two: Both teams had been the number one seed in the East (record wise), but clearly, Lebron James‘ teams got the best of them (both in the Eastern Conference Finals).
Also, each team had one true star. For Boston, it was Isaiah Thomas and for Chicago, it was Derrick Rose. Unfortunately, even with key role players, both teams were missing another star player to help push them past Lebron James.
After 2011, the Bulls tried filling talent around Rose with people like Pau Gasol.
