Wow that was an interesting play. You can watch it by going
here and then clicking on "Brackets / Games On Demand" and then the Arizona / Utah game and then click Highlights. It is near the end at with 0:38 left in the game.
The Trail (not really the "old" trail b/c the play never ended) was the one that called the travel. It also should have been a travel on the Utah player not the Arizona player but what a great job by the trail official.
Thanks for posting it!
