i do think shoe is right to an extent, different strokes for different folks (and scenarios) - especially when it comes to the question of, 'are you diligent enough to update right at midterms or are you likely to realize you have a problem after you already lost a player'.
but on the other hand, the sh issue is just one issue of a cluster of related issues. 'conservative' practice planning (high study hall, reluctance to 0 out categories, reluctance to allow off-cores to flatline or drop even temporarily to grow cores aggressively) very significantly disadvantages you when compared to aggressive practice planning. i recommend aggressively growing cores, aggressively trimming study hall, and aggressively 0ing out (or even cutting to 3ish, in some cases) categories where the return on investment is less than the return on investment elsewhere. this might mean you 0 out a blue category even, in some cases (that's rare, but you should be 0ing out lows like crazy)
i think being not-so-aggressive in 1 of those areas, with an otherwise aggressive approach, is fine. but the folks who really pushed back on the 'you can 0 out lows' thing, from my experience, tend to be the guys pushing back on the 'you can 0 out sh till midterms' thing, and the rest of the package as well. without question, the difference between aggressive and conservative practice planning can really add up. so, i'm not going to really argue about whether or not there is a viable case for not 0ing out before midterms, but i will say - if you read this and think, well i'm not really doing any of that aggressive stuff, then you should seriously reconsider. in short, your top few categories of growth for each player should be hitting 20 or more for most of your fr/so - thats an easy, half-way decent metric you can use to assess if you are being aggressive enough or not. if you are sitting there with a big with green rebounding, and you aren't at least 20 minutes, and probably ~24, then you are doing something (likely several things) wrong, and probably significantly so (outside of contrived scenarios, and probably a couple realistic but very edge case situations too).
