Regarding fantasy metrics, it is significantly flawed to look at fantasy rankings to determine the value. Fantasy valuations generally overvalue speed/stolen bases, don't factor in defense at all, don't factor in strike outs, over value power/HR, etc. Things like stolen bases and HR certainly have value, but a guy like Trea Turner(yes he's better than Adames) is wildly more valuable than Adames in a fantasy format because he hits the stolen base category hard every year. A guy like Wong is one of the best 2b in the league from a WAR perspective, but in a fantasy format i would never even consider holding him on my extremely deep 40 man roster because he doesn't have much of any SB/HR potential. At this stage a good year would be 10 of each with a 750 ops...and that's the upside.
And from a general standpoint, It's better to look at the value of the position player group vs specifically the offense, as we're pretty heavily built on run prevention. When you look at the value of our position player group, we have a guy in the top 10 at most positions. When you look strictly at offensive stats, I'd still argue Adames and Narvaez are firmly in that group with Yelich, Tellez, and maybe Urias could land in that group. Cain probably can't, Wong, probably can't, Renfroe is a longshot...but all 3 of those guys supply so much value on defense with 2 at very key defensive spots.
At the end of the day, I think we're better served to nitpick this team when we're 40 games in than 10 games in. 40 is still not a lot but the trends certainly matter more. For example, the Pirates are 5-4 currently. Does anyone want to bet they'll continue that trend through 162 games? If so, I will gladly take it for literally any amount you would like.
