Have you asked yourself why you want to introduce git if team has an alternative they prefer? The answer to that question gives you what you need, bit could allow you consider whether the trade is worth it. I have convinced gitophobes in the past, but the team was mostly on board, it was the minority that needed coaxing. That is much easier, because you can suggest trying it by working with those open to it. Generally people will cave to FOMO as others are learning together. I would also keep in mind that there is a upper limit to how much 'selling' you can do to someone, so make sure this fight is worth it before using up the political capital needed to get them there.
