Explanation? As we have seen time and time again, the referees don't see things that hit/collide with Yao, therefore, it was obviously a travel.
An aside, same game: Suns get an offensive rebound. Dribbling, pass from basket area out to Jason Richardson in upper right corner. He catches the ball a foot in front the 3 pt line, feet kinda on the ground. But then in the same motion he's senses he's in front the line then WITHOUT DRIBBLING hops back behind the line so he can shoot a 3pter? Traveling or not traveling? I guess catching a ball moving forward for a layup without dribbling and catching a ball moving backward for a 3 without dribbling is kinda the same - taking non-dribbling steps before shooting. But Yao gets a few based-on-appearance travel calls doing the same. And Wafer got a based-on-appearance call. But whatever, too inconsistently called to tell
