you can't take years past and apply it to predict current season. Yes each season itself is a small sample size, over the course of baseball history, but during the season the only thing that matters is how that season is playing out. For instance, last year HRs were off the charts to the point people were assuming the balls were juiced, yet this year offense is done and strikeouts are way up. And in fact No hitters and no hitter bids are up this year over last year.i mean you're basically putting stock into clutch and other similar baseball myths. the "this team finds ways to win" narrative isn't real. it always feels that way when you're watching a team get all the big hits and winning a bunch of close games in a short period of time, but the fact that it's happened that way so far doesn't make it any more likely to continue. it's outdated baseball rhetoric that has no evidence of being real.
I'm also not saying it has no chance of continuing for an entire season. and if it does, they deserve a certain level of credit for it. the 2016 rangers didn't "deserve" to have that kind of success, but it still earned them a lottery ticket into the playoffs, and the world series would have been very real.
But every year there's teams that are "doing things that shouldnt happen" and "should level out over the course of the season" As you mentioned the 2016 rangers were ridiculous in one run games. Last year the astros were ridiculous offense from the 7th inning and on, people in houston, sports writers/radio hosts were saying they can't ive by that, its not going to sustain, yet it did the whole season. Same thing with 2 outs and RISP they were ridiculous in those situations last year.
