Dude, Vlad hasn't even turned 22. His first two seasons have been at ages 20 and 21, following a complete and utter annihilation of the minor leagues at the ages that. Throughout the entirety of his career, most "good" prospects would either still be in college or high school, or getting what might be considered an aggressive promotion to A+/AA. He projects highly because the kind of guys that are above average hitters at 20 and 21 with good K and BB rates and decent power tend to go on to be exceptional hitters. This is not to mention that what he did in the minors and at the age that he did it is basically a Hall of Fame level talent.
For as much as the projections don't like Teoscar as much as we might, what do you expect? The entirety of his breakout came in a 50 game sample with an elevated BABIP and worse BB rate. 2020 was a small sample size, guys put up a great 2-3 months all the time and then go back to being their usual self. I hope Teoscar builds on his offensive breakout, but the truth is the most likely scenario is he's exactly who he's been his whole career, maybe a slight upgrade on that.
