I would put Allard a cut above everyone else. They break down into the following tiers:
Allard (legit 1-2 guy)
Soroka (legit 3-4 guys)
Anderson
Gohara
Newcomb (likely BP guys)
Fried
Wentz
Touki
Blair
Wisler
Muller
Sims
Sanchez
Weigel (wildcard)
Braves will be lucky to have 2 of the Allard/Soroka/Anderson/Gohara group turn into legit MLB SPs. I'm going to guess Allard ends up producing like Quintana, and Soroka puts together a Derek Lowe type career without that one huge outlier season.
They will also be lucky to have 3-4 of the next group catch on as 3+ career WAR BP arms. Whichever ones figure out their control and/or stay healthy will have a 5+ year MLB career.
This seems awfully pessimistic if you are talking stuff. If you are talking likely outcome then ok. It makes more sense to bet to lose b/c the odds are forever in your favor.
Soroka I get not putting in 1-2 b/c the stuff isn't electric.
Anderson looks like he has what you need to be a 1-2. Third pitch. Fill out. Stay healthy. There are a lot of super highly ranked guys you could say that about.
Gohara has to have a ceiling higher than 3. He's a lefty with stuff. Power stuff.
Newcombe is still a 3-4 guy to me. Even if he's nasty with a bad inning or good start/bad start he's better than a lot of guys. I think he and Folty settle into that really good 3 space with 5 awful starts a year.
Fried is a stud. I know people are down based on a couple bad starts. I get the arm history. If he's healthy he's a stud. Needs a full year at AA and AAA first.
Wentz and Muller I've never liked and would like to see hit. I don't like low velocity out of those guys.
Touki I think will either be a 1-2 or nothing. My bet is on nothing. I don't see him being a bp guy. The 1-2 potential is easily there for me.
Sims I see as a 5th starter. A good 5th starter. Maybe in that 3-4 if people think he can get more movement on his FB. I'd say 4-5 but that's not a category you listed.
Sanchez I see as nothing. It's prospect fatigue and he's still super young. But he's just a guy IMO.
Weigel I see as a 4-5 or a bp ace. is The third pitch that good to be a higher guy?
Blair and Wisler I see as maybe long relievers.
With all of these starters I'd like to see them go to a multi inning RP model. I think some of these guys could turn over a roster once pretty well. Then have Cabrera and Minter as your R/L power guys.
