The Mavs are riding an emotional high after winning their first-ever NBA title.
The reason their plane may have been late leaving Florida could be because after taking the NBA trophy from the Miami Heat the players hit South Beach to celebrate.
YouTube video shows the Mavs taking over LIV at the Fountainbleau Hotel with the Larry O'Brien Trophy and singing "We Are the Champions" at the top of their lungs.
A Miami blog has photos of the Mavs partying the night away, and instead of booing them out of the hotel, Heat fans took pictures and video of the NBA champions celebrating.
And TMZ shows Heat fan Lil' Wayne and Trey Songz partying with the champs. Dallas rapper Lil Twist, 18, was there too.
A well-deserved and earned celebration indeed. Sleep is over-rated right Mavs fans?
