ROSEVILLE — Kolton Miller saunters through the front door, all 6-foot-8, 309 pounds of him, fresh off a grueling workout with his trainer, past the signed Joe Montana and Jerry Rice jerseys framed on the wall to his right. That’s correct. The father of the Raiders’ first-round pick hangs a pair of 49ers jerseys over a billiards table covered in — you guessed it — red felt.
Miller holds no beef with Dad even if his team is Oakland’s Bay Area foe. The soft-spoken 22-year-old doesn’t hold beef with much of anyone, for that matter — not the critics saying the Raiders reached for him at No.
