@Texas Aggie, here is some video footage of why a foul should be called.
The worst foul in tournament history? Pitt’s error hands Butler win - The Dagger - NCAABBlog - Yahoo! Sports. Pause it on 26 seconds. If a foul is not called, Butler player might not secure rebound and Pitt throws up a prayer and goes in. That is why a foul should be called there.
