I don't know.....I'd like to keep Garver, but he's very valuable I'd think (esp when the DH is universal). He'd bring back a great prospect, or two good ones. I'd 100% trade Arraez if he brought back a guy you believed in. I'd consider Polanco, IF and only IF you keep Arraez or believe in Martin or Lewis at 2B, but I'd have to be blown away.
If Sano brought back a good prospect or two, I'd consider it. But, I really think he's going to come out hot this year and be worth every penny...that said, next year looks lost, and they have some hitters coming up that can't field, and Larnach is a DH imo......so, maybe? I'd hate to deal him, I'm a believer, and I don't know if you can get what I'd want.
No way I deal Jeffers at this point. He's a legit starting catcher who isn't old. I don't know if you can get enough for Kepler to make it worth doing.
BTW, there were almost no trades, so their lack of action there is not a surprise......and it may not be possible to make trades if the LOCKOUT lasts close to the season.
