I'm perfectly fine taking a chance on him in Vegas. If he sucks, he sucks. History and stats say keep Flores. He's a prospect. He has the same chance as succeeding/failing as whoever we are presumably trading him for. And considering we want young players back with not the longest track records, basically yes, I don't care if the only opportunity to trade him is lost.
Because 1B is his only logical position to play with Wright locked up forever.
He doesn't fit on this team, and he can't play 2B. Murphy is a better athlete than Flores and he's still below average at the position.
