Probably a little optimistic, but definitely promising. Albies is probably a year of good play shy of being top 100. I don't think Folty is a clear top 100 guy. Jenkins probably won't be close.
I still would consider Ruiz as close despite the tough year. Mallex will probably be clear top 100. Don't think Davidson is top 100, but he's moving in a positive direction. Peterson has kind of tailed off a bit late; hopefully just a little slump.
I think Folty is a clear top 100 guy if you still consider him a prospect. He was easily top 100 before 2014 and had a rough year last year, but was still top 100 according to mlb.com coming into this year. And this year he has flashed some great stuff in the majors. While his overall work in the majors wasn't phenomenal, I think he definitely showed enough to prove to people he can be a starter in the majors, which was the major question surrounding him. I think you would have to put him in the top 100 on potential alone.
I think Albies is a no-doubter now. Fangraphs aggressively put him 34th, and Keith Law had him in the top 100, too, I believe (maybe just really close?) and that was before he had ever played in long-season ball. Now that he has put up the year he has in A ball as one of the youngest players in the entire minor leagues, I think he's done what most were simply waiting on him to do, which is prove it against a higher level. I would be surprised if there's anyone respectable who doesn't have him in the top 100 now.
Ruiz hadn't yet been top 100 by anyone outside of maybe Fangraphs, and his year has been terrible, so I don't see any way he's in the top 100. The guys I listed as 'close' are guys I could see being put in the top 100 right now by someone.
And you may be right on Jenkins, but he's been a top 100 guy in the past at various times, and his stock shot up in the AFL last year, so I think his success in AA this year probably confirms for people that he is healthy again and progressing the way they once expected him to. The only question on him is the K rate.
