He set a record for how much data he passed in those 18 months.
And his professionalism or lack thereof is beside the point. He took it upon himself to offer classified material for sale to three foreign governments (the first two thought that he was an FBI plant). He actually sold said classified material to Israel, a foreign power.
He violated his oath to the United States.
Everything else is just arm-waving.

But as for the other stuff, armwaving and whatnot, I await with some interest what will come out of this. In particular, I'd be interested in hearing what Pollard would say once out of prison.
