There is a strong possibility the Nets will have their three superstars - James Harden, Kevin Durant and Kyrie Irving - playing together for the first time when they meet the Cavaliers today. 
Consider two things before jumping to the conclusion that the Nets are going to destroy the Cavaliers. 
No. 1: Irving hasn't played in 15 days. He's going to be rusty. Also it takes time for three players of that magnitude to get comfortable with each other on the court. This is what Nets coach Steve Nash said about that, "It's hard to build chemistry without playing, and we're not playing in practice. So the chemistry is going to be formed on the floor during games." Irving may be on a minutes restriction. It's doubtful those three mega stars are playing if Brooklyn does build a big lead leaving the back-door open for Cleveland. The teams meet again on Friday. 
No. 2: It's not getting nearly the publicity of Irving's return, but the Cavaliers are expecting to get back their injured starting backcourt of Collin Sexton and Darius Garland. Both went through full practice on Monday. Reserve guard Damyean Dotson has done a credible job filling in. Sexton is one of the more underrated players in the league averaging 25 points. Center Jarrett Allen and veteran Taurean Prince are set to make their Cleveland debuts. They were part of the Harden trade. Allen is having a good season averaging 11.2 points and 10.4 rebounds. He joins Andre Drummond, who is averaging a career-best 19.3 points and 15.8 rebounds. 
There's also the situational factor to consider. The Nets are in a letdown spot after a dramatic nationally televised two-point victory against the Bucks two nights ago. The Nets were underdogs against the Bucks. Brooklyn is 2-6 ATS the past eight times it has been favored.
