I have the Mariners pegged for about 200 home runs on the year: 60+ from Morales and Morse, about 80 from Montero, Smoak, Saunders, and Seager, and that leaves about 60 to be hit by the remaining 7 guys, an average of 9 homers each between Guti, Bay, Ibanez, Ackley, Andino, Ryan, Shoppach, and whoever gets called up.
Even if Andino, Ryan, and Ackley fall on their faces and don't get replaced, the Mariners should get pretty close to 200, so I think that's the test for how much you think the Mariner offense can achieve.
