For both ESPN and FS1/FS2, yes, you need both the Orange and Blue packages. But you get a small discount for bundling both, so the price is $40 instead of $45. So, $40 plus the $10 Sports pack to get the PAC12 networks, plus $5 for DVR = $55.
It’s still better than the $100 plus I was paying for Dish and there’s no contract. After football season I’ll drop the Orange pack so it’s just Blue + Sports.
