C - Buster Posey - The 1B Eligibility and the fact that he's younger than Mauer and a proven hitter and will play more than other everyday catchers due to how valuable his bat is to the Giants make him the best at his position to me
1B - Votto - This is a bit of a diceroll this year as to who is BEST at the position. I like Goldschmidt, and while he's young and plays in a hitter's park, I'm not sure if I'm sold on him as he doesn't have enough experience. Davis is unproven but has BIG power potential as we've seen, Prince is a coinflip after last season but is going into a hitter's ballpark and a hitter's lineup, and Edwin Encarnacion is coming off of wrist surgery. So I'm take the most consistent proven hitter out of them all. Plus Votto walks.
2B - Cano He doesn't get hurt, he always hits. At the age where he'll be hitting his prime. Maybe Kipnis will give him a run for his money since Cano is moving to a worse lineup and a pitcher's park, but I'm still taking Cano since Kipnis kind of cooled off after such a hot streak last season. Cano is just more proven as a hitter.
3B Miguel Cabrera - No contest, best hitter in the league at a slim position.
SS - Hanley Ramirez. Shortstop is yuck this year. Hanley, Reyes, and Tulo are oft-injured, Andrus has no power, Jean Segura is very young. After that not too many solid options. So I'm going with the guy who looked unbelievable when he was on the field last year. But if you ask me, I'd rather take a later-round selection on a guy like JJ Hardy or Jed Lowrie than spend a high one on a guy who might get injured.
OF - Trout. Five-tool player. Homers, Bags, Average, RBIs. #1 or #2 overall pick in all leagues. What more do you want?
OF - McCutchen. Another five-tool player. Last season he was money in the bank the whole time. Again another guy who can steal, hit homers, get on base, and drive guys in.
OF - Adam Jones - He may not walk, but that's not his mentality when he's at the plate, he's looking to drive guys in. Strikes out a lot but is a proven hitter, much more than Harper. Isn't a slouch on the bases, and hits in a good ballpark and a nice lineup.
SP - Clayton Kershaw. Should have won the NL Cy Young 3 years in a row. ERA under 3 last 3 years. Enough said.
RP - Craig Kimbrel. I hate Relief Pitchers because of how flaky they are from one year to the next (Looking at you Fernando Rodney, Grant Balfour, and co.), you can never tell what you're going to get with them. But Kimbrel has kept up his imitation of Mo Rivera for the last few years now, guy is just dominant. Not perfect, but way more consistent than the rest of the guys out there save for possibly Chapman, but he's only been closing for two years. Have to go with him.
