What happened: New York is preparing for Jaxson Dart's second NFL season. John Harbaugh took charge in January on a five-year contract.

Why it matters: Dart's development is central to the Giants' bid to improve on a 4-13 season. Harbaugh viewed the quarterback as a cornerstone when he accepted the New York job.

What to watch: Dart's preseason work will offer the first test of his adjustment to the new coaching regime.
