The Celtics' opening-night win over Miami showed that, contrary to popular belief, the Heat have not yet clinched a berth in the NBA Finals. Boston is still the beast of the East and gets its next test tonight against the always-entertaining Chicago Bulls. While star guard Derrick Rose and whirling dervish Joakim Noah seem to get better every game, the absence of free-agent signee Carlos Boozer to a finger injury makes things challenging for new coach Tom Thibodeau, who spent the last three seasons as an assistant coach in Boston. The loudest ovation at TD Garden may be reserved for former Celtics fan favorite Brian Scalabrine, a part of the Bulls' frontcourt rotation. — Roger Leister
