Here are your national experts' predictions for Heat vs. Mavs:

Charles Barkley - Mavs (Pretty sure he's the only national voice to pick them each round)
Kenny Smith - Heat
Chris Broussard - Heat in 6
Chad Ford - Heat in 6
Michael Wilbon - Heat in 7
Jack Ramsay - Heat in 6
David Aldridge - Heat in 6
Jon Barry - Mavs in 6
Tim Legler - Heat in 7
Jalen Rose - Heat in 7
HoopsWorld - Six pick Heat, two pick Mavs
ProBasketballTalk (NBC) - Heat in 6
Marc Stein - Mavs in 6
WhatIfSports - Heat in 7
Henry Abbott - Heat in 6
Chris Sheridan - Mavs in 7
JA Adande - Mavs in 6
Tim McMahon - Mavs in 7 (bad sign)
John Hollinger - Heat in 6 (also, Blazers in 6, Lakers in 5)
Greg Anthony - Blazers in 6 (whoops, that was first round)
Adrian Wojnarowski - Blazers in 4 (same thing)

With local guy Tim McMahon excluded, that is 18 picks of the Heat, 7 for the Mavericks. Let's hope the national consensus does not have a feel for this one.
