By "Team" I assume you mean the Brewers. If the Brewers need an OF next year, it's quite likely that Hart would have moved to CF, vacating the RF position. You kind of contradict yourself there. Also, CF is higher up in the defensive spectrum than RF. Sure, balls won't tail as much as they do in the corners, but there is an awful lot more ground to cover and you need to be able to get a really good read and jump on balls to succeed in CF.
