Sometimes I think that BABIP is one of those metrics that no one cared about for too long, but now everyone cares about too much, without taking the time to dig deeper. Like, should it generally be expected to regress? Sure, but not always to the same point. Duran had a .381 BABIP last year, which is obviously not sustainable, but his average over time is .347, and all of the project systems have him at around .330 for next year, so it isn't like he should be expected to drop to .300 or anything close to league average.
He has a sprint speed in the 96th percentile, and a hard hit rate in 77th percentile, according to statcast, leading to an xBA of .268 (73rd percentile). Granted, that doesn't make him a great player with a bat in his hands (even with a significant baserunning value), but it adds up to a guy who should be slightly above average overall, assuming a below average glove, which isn't a given.
Not saying that he is an all-star, but if he is even just that, it's absolutely a player with value prior to FA. Let's not be in a huge hurry to get rid of him 'because BABIP.'
