Here is my thang...
Kipnis is going to be a regular Top 5 2B'r in fantasy. Two full years...its looking like two straight years of being Top 5 at his position, with spurts of being a legit top guy (I'm curious how he closes this season, as last year, he dragged ass a bit late).
Upton is very good, but he walks a fine line between being a great outfielder in fantasy and a JAG. He's only 25, but he's got himself quite the mixture of great seasons and mediocre seasons in him...if he either finds a consistency between great and JAG...good, otherwise, ol boy might be a headache. Personally, Kipnis for Upton, right now...would be a push at best. If you aren't a great OF'r, you are kind of a dime a dozen in fantasy.
Latos is a very good fantasy starting pitcher, and Johnson is a bum until otherwise noted. He hasn't been a legit stud since 2010 considering the injuries and shit seasons he's had.
Profar is as good of a fantasy lotto ticket as you can get right now.
