Here's a question that maybe belongs in another thread but relates to what you say: Has baseball changed in a way that makes acquiring FA SPs much harder? Specifically the emphasis on high-effort, high velocity pitching leaves very few reliable arms available into their 30s. The early lockup contracts are one factor, skimming a few elite guys off the market. And the ones left are guys like Snell, Rodon, etc., guys who have injury concerns or velocity drops from the early wear and tear. Bloom doesn't literally "love injured guys" as mentioned above, he was a GM of a team that needed starters off the market and there were never enough uninjured FAs worth the cost.
Great question, I think the answer is definitely yes. There are fewer starters in general (with the move towards openers), fewer good starters in general, I think, so fewer good free agent starters- and like you said, they all come with flaws. Bloom did a pretty good job, i suspect, at signing free agent starters- Kluber was the only real bust even if most guys he got were only average-ish.
It seems like the days of trading for a small market teams young starter (Pedro, Beckett, etc) before they get expensive is also much less of a thing- in large part, it seems like the weaker small market teams don’t even have guys like this and in the few instances in which they do, the prices are so high because such players are scarce.
The most wins for active pitchers under 30….Aaron Nola (90), Jose Berrios (83), EdRo (80), Blake Snell (71), Taijuan Walker (69), and German Marquez (65). Kind of a weird list, no? I guess the definition of a “top of the rotation” starter is probably none that need to be recalibrated.
So you really need to develop pitching form within, I think. But if you aren’t…and want to contend, what’s the solution? Delving into the FA marketplace that’s riskier than before? Trying to make trades which are harder to pull off (and probably more so when you don’t have pitching prospects to deal)?
good luck to the next guy.
