We have better depth than almost every other team. I'm not sure what the criteria is for "quality depth," as by definition, they are not starters. Last year, Houck was views as our 6th starter and Criswell our 8th or 9th. Rafaela, Abreu and DHam were viewed as role players or "depth."
This year, we can view Crawford or Gio as our 6th starter. Both have a higher projected fWAR than any other team's 6th starter. If that is not "quality," what is? Criswell, Fitts, Priester and Dobbins are our 7-10 on the depth chart. I doubt anyone has much better than that, unless they are injured pitchers on the depth chart.
Our pen has incredible depth, but I would agree with your point, here, and ask, how much of the depth is "quality/" We also lack a true lockdown closer, but maybe Chapman, Hendriks, Slaten or Whitlock can step up a slot and do okay. While many of the pen depth chart do not look "quality," so many have some level of promise, and there are so many of them, that it's hard to imagine almost all of them having a bad year, at once:
The likely 7: (not counting our 6th starter as a pen arm) Hendriks, Chapman, Slaten, Whitlock, Wink, Weissert & Wilson.
Pen depth: Bernardino was pretty damn good from 2023 to midway into 2024. Kelly & Penrod showed signs of promise in '24. We can convert a AAA SP'er to the pen: Criswell, Fitts, Priester, Dobbins and Fulmer. I Campbell has real promise. (Drohan and Gambrel are long shots.) The rest are fringe or just hopefuls, but some have shown clear skills: Jovani Moran, Wyatt Mills, Bryan Mata, Noah Davis, Robert Stock, Sean Newcomb, Hobie Harris, Wyatt Olds and AA pitchers like Sandlin, Cruz, Webb, Hoppe, Troye and Celluci coudl rise. We don't even need 10-15% of these fringe guys to do well.
Our depth at the everyday positions is largely speculative, when it comes to our top 3 prospects, but what team has 3 top everyday prospects as highly ranked as ours? I think you have to call them quality, of nobody can say they have it.
Our catcher depth is not "quality," but it could be decent: Narvaez, Sabol, Zavala (Jo Garcia is too far away to count.)
1B depth depends on Devers being handed a 1Bman's mitt or not. (Romy & Wong are the depth, now.) We might need another Dom Smith type, if Casas goes down.
2B is loaded with good depth. Campbell, DHam, Romy, Grissom, Rafaela and either Story or Mayer.
SS has Mayer, but then it's Romy or Rafaela. Still, that looks close to quality as you can get.
3B now has Devers w Bregman, so it has greatly improved. (Romy and Campbell might be the only other real depth at 3B.)
OF is loaded, despite losing O'Neal and not signing anyone. Projections for our OF seem very low, to me, but we had one of MLB's best hitting and defensive OFs in 2024, and most are still moving towards prime: Duran, Abreu, Rafaela, Refsnyder, Yoshida and maybe Romy, Grissom or DHam can learn to play OF. Then there are Anthony and Campbell capable of winning a FT role and doing well. That looks top quality, to me.
