School is out for the summer.

There is no doubt over the past nine weeks that professor John Harbaugh has imparted a great many lessons to the 90 pupils in his class. There also is no doubt the students taught Harbaugh a thing or two about what to expect from them when everyone reassembles in late July.

Harbaugh was officially hired Jan. 20, and immediately started to gain as much intel as he could about the players he inherited on the roster. Three months later, the bulk of the indoctrination commenced.

The Giants opened their offseason program April 7 and closed it down June 10. In between, there were loads of individual drills and offensive, defensive and special-teams meetings, followed by team work on the field, 10 organized team activity practices and a mandatory three-day minicamp. Through it all, no shoulder pads were worn and no hitting was allowed. But the framework for how the Giants will operate this season was installed.
