The Oakland Raiders always appeared to be the logical team to be featured on HBO’s Hard Knocks, and on Tuesday, that became a reality. When you take one new GM, three first-round draft picks, a revamped wide receiver corp, exciting secondary battles, three countries, an offensive guard with a bad temper, Derek Carr in comeback mode, Antonio Brown with a visible chip on his shoulder, three countries to play in, four time zones and Jon Gruden, you mix it all together and sprinkle a generous helping of HBO Hard Knocks top for the recipe for ratings success.
