The Raiders have an interesting preseason ahead. They have three exhibition games on the road, including one in Canada. They’re headed to Napa for camp, which is possibly, though ultimately uncertain, the last time they will train in Wine Country, with their Las Vegas relocation scheduled for next year.

They have personalities to spare on this unit, which must bond to improve on last year’s 4-12 disappointment. They’ll do so under NFL Films’ watchful eye, with cameras everywhere filming this season’s HBO documentary series “Hard Knocks.”
