It was a mad scramble with a lot of contact, but it looked like a form tackle on the replay.
What I don't understand is all the talking heads that say "Let the players decide the game." What are the refs supposed to do, suspend the rules and allow anarchy on the final possession????
...and while I'm on the subject, is there a more collectively horrible group of studio commentators than those that show up once a year to do the NCAA Women's Tournament on ESPN?? They have absolutely nothing insightful to say.
