1. I don't think this will happen, and is probably just the Braves trying to drive the price of Adam's up for teams that want him with the "Fine, we'll just keep him." bluff.
2. It's not "so" far fetched because Freddie was a 3rd baseman. He knows the position and was probably moved because they had Chipper. Let's say he's horrible. We probably win a few games with Adams bat and loose a few with Freddie's mishaps at 3rd. It's probably a wash and even if it looses us a few...just gives us a better draft pick. We then keep Adams as a bench bat or trade him in the offseason.
3. I doubt it happens, but a lineup with Adams, Kemp and Freddie in the middle (assuming Adams doesn't regress...which is possible), would be pretty nasty. Where is the weak spot 1-8 with Dansby hitting now.
The only way Adams doesn't regress is if he suddenly has more power than guys like Stanton and Sano and Judge, and continues at a 27% HR/FB rate.
Anyone saying Adams is a .900+ OPS true talent hitter is saying he suddenly has the best power in the game.
