While Aroldis Chapman, whom the New York Yankees acquired in a five-player deal Monday, is one of the best one-inning relievers we've ever seen, he faces both a legal investigation into a domestic violence allegation and an MLB investigation that could result in a lengthy suspension. The Reds' return in Monday's trade reflects the possibility that he'll be charged and/or suspended.

There's no question that Chapman is the most valuable reliever in the game today. He has the hardest fastball in baseball history, misses tons of bats and can probably handle outings of longer than one inning as well as any closer in the game due to his history as a starter without serious injury. (He did have a bout of shoulder soreness a few years ago when the Cincinnati Reds tried to convert him back to starting.) Since Chapman became a full-time big leaguer in 2012, he has produced more WAR than any reliever by Fangraphs' FIP-based calculation, and he is in a dead heat with Craig Kimbrel over that span via Baseball-Reference's ERA-based calculation (Chapman has thrown five more innings). Bottom line: He's good, and if the Yankees keep him, Andrew Miller and Dellin Betances, they may have the majors' best bullpen ever.

But Chapman has been accused of domestic violence, and if an MLB investigation finds those charges have merit -- even if the evidence might not support a criminal case against him -- Chapman shouldn't throw a pitch for the Yankees in 2016. Commissioner Rob Manfred has a few cases in front of him now, including this one and the Jose Reyes incident, in which he can set a precedent for future domestic violence cases, and he needs to drop the hammer.

If I were a general manager, I would have zero interest in having a player who has either committed or been accused of domestic violence or sexual assault on my roster, regardless of his talent. Baseball is a business that depends on the public to buy into its product, whether we're talking tickets, merchandise or broadcasts. Continuing to employ and play players linked to these egregious acts sends the wrong message to female fans and is both bad business and ultimately a moral failure. Should Chapman be forced to miss 50 or 100 games in 2016, it would only serve the Yankees right for acquiring him. And if it turns out that he did assault his girlfriend, the Yankees should be ashamed of themselves for acquiring Chapman when they knew this might be the case.

The Reds must have wanted to get rid of him, as the package they got in return is all quantity but little quality. Rookie Davis has a chance to be an average starter, possessing a 92-95-mph fastball and above-average command but no pitch that's clearly above average right now. I'd project him to be a No. 4 starter in a typical MLB rotation. … Caleb Cotham, who has above-average control of an average fastball and potentially plus slider, should go right into the Reds' bullpen. He had no platoon split in the minors but struggled a bit with lefties in the majors in a tiny sample. … Eric Jagielo, a first-round pick in the 2013 draft, projects to hit in the high .200s with 18-20 homer potential at his peak, but he can't play third base and has been injured in both of his full pro seasons. … Tony Renda is an organizational player whose only notable skill is a high contact rate; he lacks any power or speed and is a poor defender at second base. … Let's not forget outfielder Jake Cave, who was plucked from the Yankees' organization by the Reds in the Rule 5 draft earlier this month. He's a quality fourth outfielder type, a decent athlete without any standout tools, capable of handling center field on a part-time basis but lacking the power to play anywhere every day.

That's just not enough for a player of Chapman's caliber, even for just one year, until you consider the possible criminal charges and MLB suspension hanging over Chapman's head. The Reds might have simply decided they'd rather turn the page on the player, likely knowing as much as anyone about his character, and save the likely $13 million or more he'll make in 2016 rather than wait out the process and see if they could get more back in the spring.
