It'd be great if Perez could establish himself as a solid back-end starter. He could either hold down a rotation spot here for a few years or we could flip him as other pitching prospects become ready.
I'm unconvinced at this point, though. 19:12 is not exactly a great ratio and he doesn't have great stuff.
I'll tell you another thing. Given the choice between Perez, whom I'm sure Sabre folks would call a "low ceiling" guy, and those "next men up" - Sims, Foltynewicz, and Newcomb - that's a slam dunk for me. I'll take Perez - a grinder, a gamer who gets guys out. You can keep your guys who light up the radar gun and can't find home plate. When the other guys get down below 4 BB/9 I'm interested. I do acknowledge that happens sometimes and that's part of the point of a farm, but I really value command.
I'm not sure I agree with your analysis. Consider these three pitchers with these three career BB/K ratios:
2.4/5.1
2.6/6.0
3.5/4.5
Not terribly inspiring, eh? Hardly overpowering.
The first two won 436 games and pitched 36 years in the big leagues, eight all star appearances between them with low 3.00s ERAs. The last was a very successful low 3.00s reliever for a dozen years who happens to have been our pitching coach for the last decade.
The common thread? All sinkerballers. The only lasting exception to a 3:1 K/BB ratio and >7.5 K/9 is an excellent sinker. And we can critique Baby Harang's physique and ratios all we want, but he still throws a heavy ball at 94. He is an uncomfortable, beestinging mofo.

welllll, those are different eras.
The avg K/BB rate right over the past 10 years in MLB is : 8.07 K/9 and 3.18 BB/9 (Perez is 5.33 K/9 and 3.65 BB/9)
during Roger McDowell's career the avg was : 6.18 K/9 to 3.20 BB/9
during Reuchels' career avg was around 5 K/9 and around 3.30 BB/9
and during Huddy's career, league avg was 6.70 K/9 and 3.35 BB/9
so, you see if you look at their performances relative to avg, they aren't as far away from league avg as Perez is.
One other thing is Huddy's career GB% was 58% (no GB% available for the other 2) Perez's GB% is 53.5 in a SSS and his HR/FB is a low 6.3% (avg is 10%) I worry that when Perez has his HR rate regress to the mean, he will need to count on his defense a helluva lot to be successful as he won't be able to fall back on K's or weak flyballs to help him out.
but maybe he can, stranger things have happened.
EDIT: interesting to call him "Baby Harang" because Harang struck guys out at a 7.14 clip per 9 over his career, his good years are always either above that mark, or his HR/FB had a below avg season.
apparently not! lol! explain?

I don't think you will find a "sabre folk" out there that will actually prefer the player that's walking 4 per 9. This preference comes from what the scouts say about their upside rather than what the stats are saying.
I value the rebuttal regarding his ratios, I think it is a solid argument worth considering. However, much like the upside guys in AA/AAA, Perez needs to make adjustments and improve in order to have a successful major league career. You can't really just bet on being Tim Hudson and having a batted ball profile that overcomes an inability to strike batters out at a high level. Maybe he continues to develop and that's his future, but I'm not banking on it any more than I'm banking on Newcomb or Touki suddenly learning to find the zone with regularity. Hopefully one or more of those things happen.
I like Perez and would like to see him stick in the rotation, BUT, he has some issues with command in an era where K's and BB's really matter a lot. If he can keep his FIP around 4.00 (and his ERA too) he has value, but he has tended to be very good and then get absolutely rocked on other days. If you don't have great command, it becomes difficult to get away with not striking out 7 per 9 innings.
I think he's long relief or trade bait, I just think Ellis, Jenkins, and gant are better
That said. If we vastly upgrade our defense with Swanson albies and a legit defensive 3b then the sinker may play up
