The young Nets have some growing pains, especially on the defensive side of the floor. The Newark Star-Ledger reports: If you ask Lawrence Frank where his team is going wrong, he’ll pull out a list. The majority of the Nets’ problems pertain to their youth — lacking an understanding of positioning and tendencies, leading to game plan mistakes and bad technique and despair — and he is convinced they’ll solve them in time. But aggressiveness is also an issue. Fact: In their first three games, Nets defenders have drawn a total of five charging fouls, even though they’ve had roughly 40 chances to draw one.
