Noah for DPOY? Bulls for spoiler?
That Indiana Pacers-Miami Heat matchup in the Eastern Conference finals is looking less inevitable by the day. Not that it isn't still overwhelmingly likely, but consider: The Brooklyn Nets on Wednesday moved to 3-0 vs. Miami this season, and the Chicago Bulls on Thursday hammered the formidable Houston Rockets to make a "remember us?" statement. A lot of the latter team's recent success is due to Joakim Noah, a popular No. 3 MVP pick and possible NBA Defensive Player of the Year front-runner. What do you make of it all?
Panthers release Steve Smith
Steve Smith's time with the Panthers has come to an end. The team released him on Thursday after 13 years of service. Smith has often been one of the most electrifying and competitive receivers in the league, but his 2013 season was subpar: only 745 yards and a mere four touchdown receptions. The Panthers are looking at Hakeem Nicks as a possible replacement, while teams like the Ravens and Buccaneers might make Smith's free agency period quite brief.
Nets knock off Heat
On January 1, the Nets were 10-21 and way out of anyone's idea of a playoff race. Since then, however, they've gone 23-9 (the best record in the Eastern Conference during that time) and are looking like the team no one wants to play in the postseason. Just ask the Heat, who lost for the third time this season against the Nets on Wednesday night. Miami fans are probably sick to death of Jason Kidd -- in his last 24 games as a player or coach, he's 19-5 against the Heat.

NBA teams tanking or rebuilding?
"Tanking" has been a buzzword this season in the NBA, what with a talented 2014 draft class coming and teams such as the Philadelphia 76ers placing little emphasis on winning now. But new commissioner Adam Silver refuses to use the word, instead calling the process of trading veterans for picks, young players and cap room "rebuilding." No matter the term, it certainly is a polarizing subject. It's no fun to watch your team lose, but it's also hard to deny the success of some recent rebuild/tank jobs, not to mention the fact that certain moribund teams (Cleveland Cavaliers, Milwaukee Bucks) actually tried to make the playoffs. What say you?
