But you gotta gauge the risk. If a guy is a known woman beater, and you have a major history in that regard on your team, you just can't. There is a thing called press, and the ravens don't want to be known to condone domestic violence by employing players convicted of it. After trying to cover up the ray rice scandal they can't afford to do this. And they shouldn't. Guys who do this really don't deserve the chance of a lifetime to make millions playing a game.
For other teams, you decide whether or not it's worth the risk. Doesn't matter if he's an all pro for his first 2 years if he decides to beat up his girlfriend and get put out of the league after. It's like if doctors tell a team that Jonathan Allen won't finish out a rookie contract and could often be inhibited by his arthritis in his shoulder, you don't draft the guy top 5 on the chance that the doctors are wrong, you gauge the risk vs reward and decide if you can afford to miss on that pick when he sits 6 games a year for 4 seasons and then retires. When that happens you can't throw your hands up and act surprised, it was a dumb pick because you knew it would happen. Same applies to bonehead repeat offending woman beaters
