1) Can Pacers stay unbeaten? The Pacers are the one remaining undefeated team in the NBA and are feeling good about themselves — but they have a tough back-to-back this weekend. Friday night they host Toronto — a team that has a center in Jonas Valanciunas that can test Roy Hibbert in the paint, plus they have shooters like Rudy Gay and DeMar DeRozan who can get hot.
2) How will the Knicks look without Tyson Chandler? The Knicks are already 1-3, having to have team meetings and now have lost center and defensive anchor Tyson Chandler for at least a month.
3) A Clippers/Rockets rematch Saturday night. Before the season started the Clippers and Rockets were thought of as potential contenders out of the West — and they both are, we’re not even two weeks into the season and teams will evolve and change over the course of the next six months.
