Sure, but ask yourself this. Is this really the best offense in baseball? Sure, it might be, but most likely it isn't. And in any case, usually being #1 is fleeting at best.
well, you're cherry picking the second half offensive stats to justify regression for their season stats (7th overall)... It's an odd argument, to say the least. Any offense can get hot for a month, but I do think there's something to be said for the fact that they were the best offense in baseball for half the season, and given their age, I think it's very reasonable for the offense to take a step forward in 2018. Can they finish with the number 1 offense in baseball next year? Probably not, but there is enough youth/ceiling there where it's possible, and even if they aren't 1, they could still finish well above their 2017 line of 7 overall.
There were no 2009 Joe Mauers putting up gaudy stats. The young kids all took big steps forward. Mauer was the only real surprise in the offense, and he didn't put up numbers outside his career norms. He simply did better than he's done the last few years. So yeah, I think improvement from 7 overall is pretty reasonable. The problem, as we all know, is pitching.
