Just one man's opinion but FG's Kylie McDaniels with his take:
"Running a team costs anywhere from 500k to $1M a year depending on the exact situation.
I’ve been stumping on here for awhile that every team should have at least 2-3 DSL teams and really should have more like 5-6. If you have a successful int’l dept, you won’t have to wait long to see value created. You’d have to add some lower level american clubs as an on-ramp to the higher leagues."
https://blogs.fangraphs.com/kiley-mcdaniel-chat-3-6-19/Basically he's saying additional teams pay for themselves given that the more players you have in your system the more prospects you're eventually going to develop.
And remember you can sign as many international players as you want with bonus amounts up to $10K without counting against your international pool and as many domestic amateur players as you want up to $125K without counting against your draft pool. [As an aside, that discrepancy on max bonuses between int'l and US players makes absolutely no fucking sense. At the very goddamn least, increase the max on int'l players to at least $25K.]
I have no idea whether Kylie is right or wrong but it sure as hell is one fucking seductive argument. Which again leads back to the question numerous folks on the board have asked: why did the Astros decide to eliminate one DSL club and their Appy club last year? If you trust your analytics dept, if you trust your amateur scouts, if your organization has an extremely good reputation for developing players (particularly pitchers) , then why not increase your odds by adding rather than subtracting clubs?
If they do decide to reverse course and add clubs rather than subtracting, the Astros could hold down costs a bit by (in addition to adding a DSL club or two) adding a 2nd club in the GCL rather than trying to return to the the Appy. That certainly would hold down travel and administrative costs. The Yankees, Tigers and Phillies already have multiple teams in the GCL while the Padres, Cubs, Indians and Giants have done so in the AZL. And I think I read some other organizations were planning to do so for 2019.
Anyway, if I've touched on these issues previously, then just call this my annual rant.
