There isn't a ton to say about these guys. They're both great, and they're both going to get a ton of money this offseason. For Price, all signs are pointing to him signing with the Cubs. As for Greinke, I would be very surprised if he did anything but the stay with the Dodgers. For the most part, I'm against giving pitchers big contracts. They almost always end badly. That said, if they sign with the Cubs and Dodgers respectively, it won't be too bad because those are both teams who have chances to make the playoffs during their time there. Bottom line: If you have a roster with a chance to go all the way soon, go ahead and sign him, if not, don't. It will end badly.
Cueto self-destructed during the last half of the season, but because of two good starts in the playoffs, he's going to get paid like none of that happened. As ridiculous as that sounds, it's still a good gamble. He's only 29 and his time with the Royals could have been just a hiccup. As I mentioned, above, it's rarely a good idea to sign a pitcher to a long contract, but teams may have no choice for him. He'll get a big deal from someone contending.
His performance the last few years makes him an ideal fit for the Yomuri Giants of the Nippon Baseball League in Japan.
Much like everyone else on the Nats, Zimmermann had an underwhelming season last year, going 13-10 with a 3.66 ERA. That said, even if he never comes back to his 2014 form, he's a reliable number two or three starter for any team looking for a starter but doesn't want to spend a ton of money, like Baltimore.
Wieters will never fulfill the expectations people had for him as a rookie, but he's a solid bat from the catching position if he's healthy, batting a career .258/.320/.422. The Twins have been rumored to be interested in getting him, needing somebody after Kurt Suzuki's disastrous season. Wieters excels in Suzuki's biggest weakness (and there are a lot of them) which is throwing out runners. Wieters threw out 31% last year, which would've been eighth in the league if he had qualified. I wouldn't be surprised if he got around three years for 31 million.
After and unprecedented 53 homer season in 2013 and the follow up year from hell, we have a pretty good idea of who he is. He'll give you power, walks and not a lot else.
The second half MVP is drawing interest from the Giants and Angels among others. He's a candidate to get 200 million.
Span was on of the reasons the Nationals disappointed so much last year, injuries forced him to play just 61 games. He was steady in those, however, batting .301/.365/.431. The Mets are supposedly interested in him. If he goes there he'll likely get something like the 4 year $60 Million deal they gave Curtis Granderson.
Fowler is an interesting case. Along with having one of the best names in the league, he's flown under the radar for several years now, as a leadoff hitter and speed threat for several horrible Rockies and one Astros team. That changed this year when he was the catalyst for the power-hitting Cubs. He'll be 30 next year, so he should be good for the next few years.
Heyward's been in the league so long it's easy to forget he's only 26. Up until last year he was underperforming, always playing solid, but being capable of doing so much more. Last year he received whatever treatment the Cardinals give all of their players and became the guy he's been teasing us with since 2010: The statistician's best friend who draws a ton of walks, steal bases and cover a ton of ground in center field. I'd argue that he has the most value of anyone in this class.
If I were a GM, there would be several rules I'd have for myself which I would make sure never to break. These are things like "don't sign a pitcher for longer than four years unless you absolutely have to" and "Don't give up on your prospects too soon". I mention this because another one of them would be "never sign or trade for a member of the Upton family under any circumstances". The are unrelentingly inconsistent, sign them and they will disappoint. Some sucker will give Justin 100 million. I'm betting on the Nationals. After a season from hell last year, Mike Rizzo is going to be making some big move this offseason, and they've got the money for it.
