These NBA conference semifinals are fit to be tied.
Four series, all knotted at one game apiece, the first time that's ever happened in the second round of the NBA playoffs under the current league format, according to STATS LLC. For favorites like Miami, New York, San Antonio and Oklahoma City, home-court advantage has disappeared, and now underdogs can control their own fates simply by taking care of business on their home floors.
Easier said than done, naturally.
The Heat, Knicks, Spurs and Thunder are four of the league's top five winningest road teams this season — which probably isn't great news for Chicago, Indiana, Golden State and Memphis, the lower-seeded clubs who will all be hosting pivotal Game 3's when NBA playoff action resumes on Friday and Saturday.
