uzr will most assuredly hate kris bryant next year, but that's because uzr sucks for 3rd base year to year. barring injury or indifference, we should expect him to stay stable for a few years in terms of defensive contribution. he's not going to be a butcher and he's not going to be machado, so i'm of the inclination it's not particularly worth much consideration. if we become more gb heavy as a pitching staff, it might be worth a little more attention the primary problem as far as i can tell (and this is nothing new) with bryant in terms of future development is that his biggest weakness is that he misses the baseball on 1/3 of his swings. while we see contact% improve with age through 28/29, it correlates so highly year to year that those improvements are likely to be very small. we should also see some improvement in strike zone judgement, particularly with relation to swings and misses on pitches outside the zone. if not cancelled out by negative variance, the convergence of these two minor trends over the next several years will give bryant more opportunities to express his dong abilities. will this equate to an improvement on the magnitude of 1 or 2 additional war? i honestly have no idea, maybe someone does anyway, leaps in contact% do occur, but i haven't seen anything suggesting that they are sustainable. and anecdotally, they don't seem to correlate strongly with increases in war but that observation is useless because it was just me cherry-picking a few names to see how those differences manifest themselves the positive outliers to the trends on contact% and plate discipline are very rare. perhaps there's an argument to be made that bryant is more likely than the rest of the field to be one of those positive outliers, but i'm not the one to make it
