They ended up using the tackle I think in the final version. The original plan I think was for Tiger to throw or hit a ball after the guy, I don't think anyone expected him to tackle, would have risked injury or something crazy.
If you watch the version where he throws a ball, it's just lame:http://www.youtube.com/watch?v=N1E3haEB5RE&NR=1

I think Tiger knew they needed to do something better than throwing a ball...
