These are nice shots, but you're shooting in a pro arena with much better lighting than one would encounter in the typical highschool/youth league/small college gym. This allows you to use lower iso's. If you're not in a pro arena, you'll still have to follow the advaice given the original poster.
By the way, go Sixers!! I grew up watching Dr J, Andrew Toney, Mo Cheeks and Moses. The last Philly team to win a title, which was 25 years ago this year
