Nothing But Net

Normal Sudoku rules apply. Numbers on arrows sum to the number in the arrow's circle. Numbers may repeat on arrows, if other rules allow. The given 8 and 9 arrows are 5 in length. All other arrows are 1 or 2 in length. The numbers on the top of the basketball (yellow line) are at least 5 apart from their neighbors on the line. The numbers on the bottom of the basketball (brown line) are consecutive with their neighbors on the line. Numbers may not repeat on the brown line. The center (orange line) is only decorative to show the basketball rim. Extra points if you finish boxes 4, 5, 6, 7, 8 and 9 (the net) first, with no numbers filled in boxes 1, 2 and 3 yet.
