The difference in strategies
Exactly. If you simply think that the playoffs are a crap shoot then you would be inclined to prefer the sustained success model. I don't believe that it's a crapshoot. Most people rank teams by their 162 game season record and that's the basis for the idea that it's a crapshoot (I don't know how fangraphs or 538 bases their odds). The problem with that is there are a myriad of reasons why a very good/the best team over the entire season would end up with 93 wins while another team has 101. Injuries and schedule are 2 as is the team makeup for the playoffs compared to the regular season (trades/acquisitions). As we have seen this year, the Brewers have an advantage because of the unbalanced schedule and their competition in the NL Central. That difference could lead to multiple game swing in wins compared to a team that is better in talent in a tougher division. Simply ranking by regular season wins ends up leading to a misconception about the "rankings". Some teams have a really bad year for injuries and end up with a worse record than their talent when some of those players return for the post-season or the opposite, a team with a great record could have players with nagging injuries come playoff time that impact their ability to perform at the level they did during the season. Deadline trades and acquisitions clearly have an impact on team talent that only impacts the roughly last 60 games. The key to the Braves success last year was in the talent added at the trade deadline or in-season callups/injury. The other factor is that the regular season record often is the cumulative effect of most of the 40-man roster as teams have injuries, add/lose players at the fringe of the 26 man, etc. In the playoffs the bench and back end relievers/starters are not used as much as most teams go with the top 9 batters and usually a 3 or 4 man rotation of the best SP and a shortened bullpen. That needs to be part of the analysis as to how teams are ranked. The Brewers do well using that depth, especially previously with expanded september rosters, but that won't help in the playoffs. The playoffs are pitting the best teams so the talent level is closer so some of the outcomes can come down to chance (the most recent example was Daniel Murphy's error 7 years ago for the Mets). The Dodgers have had a long run of making the playoffs, but outside of the pandemic year have not won anything. What would happen if Corbin Burnes pitched like Jason Alexander during the playoffs? Probably what has been happening to the Dodgers with Clayton Kershaw, He hasn't been horrible every game, but when your TOR starter is blowing up a game a series that's a big impact when you are playing a team with similar talent. But that is likely to determine 1 series, not every one and now with the expanded playoffs 3 series gets you to the World Series (2 for the 2 top teams in each league), which makes a chance driven outcome harder 3 series in a row. I met a statistician/data modeler through work that basically taught me there is some chance in everything that humans do, but there is a lot of activities that can be modelled with enough information those models are more accurate. Over drinks he told me that anyone who tells you anything in life (outside of games of chance) is all based on chance hasn't looked at enough data.
