It all depends on KG and Rondo, IMHO. If those two are healthy and engaged, respectively, for the full season, then we have the best shot of anyone in the league. Those two are the biggest keys to our defense, rebounding and hustle play. Their contributions made 27-2 possible. When you have that level of intensity and hustle, it makes the game fun and important for the whole roster and smooths over the inevitable rough shooting nights and butterfinger follies that would doom more lackadaisical teams.
I'm optimistic about KG's health and Rondo's focus this year. The team's depth will allow the team to maintain intensity without as much burnout, while the presence of Sheed and Daniels off the bench alongside Scal, House and Tony anchors the team with more gray hairs to minimize distractions and help keep the younger guys like Rondo from isolating and pursuing separate agendas.
