Are his constant injuries and his health good signs too? We don't HAVE to trade him. But that's not bad value(and it doesn't need to be a prospect, just that value equivalent) If we keep Dex, its not a horrible idea to look at the pitching he can net. If Candelario nets us the same, fine, look at moving him. But, looking at moving Soler isn't ridiculous at all. He's not very important to us, if we keep Dex. Even if he misses 80 games every year (like he did this year) he's still a surplus value for the next 4 years. You won't get that back in trade so yes it's stupid to trade him just because you can. That's why people who win the lottery go broke quickly.
