As they note, they benchmark their methods against trades that are actually made and continue to refine their models. As they note under their "History" page:Goldfan wrote: ↑06 Dec 2025 07:59 amAs I thought….a bunch of assumptions…..projections…..some tied to WAR….over simplification……attempting to spit out a single number that somehow takes in to account the motivation, needs, financial capacity, of one organization vs another organization. I don’t think this is how trades work in the real world.mattmitchl44 wrote: ↑06 Dec 2025 07:50 amHere:Goldfan wrote: ↑06 Dec 2025 07:44 amSo do all MLB teams have this BTV book and this is how trades Finalize……..Only if these values somehow align?? The Sox want to win now and required a top of rotation SP. The Cards received a minor leaguer and a bottom rotation starter. Sox don’t care about Grays age or salary wanting to win now. Cards are rebuilding on hope and not MLB production. New Cards players may NEVER produce a MLB return. Completely different NEEDS for each team. So how does this correlate to some BTV value?ICCFIM2 wrote: ↑06 Dec 2025 01:23 amCertainly that is true. The math from the first trade by Bloom probably points to the equations he is using to win this game. He gave up $10.6M of value in the Gray trade and received $23.7M of value per BTV or $13.1M of excess value. I am guessing by running up the bidding on Donovan, he is trying to receive more than $13.1M of excess value on the Donovan trade, if it happens. Presumably if enough excess value trades are made, the percentage increases that enough of the prospects come through it is a winning situation over time.brock118 wrote: ↑05 Dec 2025 22:59 pmThat's why it is so hard to rebuild small room for error.

But, the Dodgers were reported to have non-national tv revenues of $300M+ for 2025 compared to the Cards $55M. The Yankees, Mets, Phillies were all in excess of $100M and maybe much more.
The Cardinals will never compete with the Dodgers, Yankees or Mets based on revenue and likely never resources provided by the owners either. Unless baseball miraculously puts a salary cap on, that means the Cardinals will be outspent by $100M+ annually by at least those teams if not other teams. Only way to compete will be savvy prospect identification and development and savvy trades. That is a hard way to make a living when those teams are also outspending the Cards on resources in those areas as well. To be honest, the Cards will need to hit a HR every other draft, which based on what we have seen the last 20 years is almost impossible to do.
Its fascinating looking at all the proposed Donovan trades on BTV right now. Some of the posters have the Cards receiving less back than what they trade away. I can't see 1 single possibility of that happening. Almost all of them equalize out the trade value with a quantity for quality trade. I can't see that happening either.
55 Grade prospects have values all over the place on BTV ranging from about $12M to $30M+. I would guess Bloom is going to try and get 2 55s at least for Donovan if not more with a total BTV somewhere in the $42-48M range. I don't know how many more, if any, trades the Cards have to create that differential. But, if he can get to the same level with Donovan as he did with Gray and maybe another 55 for Contreras, then the Cards have reduced the roster valuation difference over time by $25-40M via trades. Of course they won't all work out. But, if they end up with 5 high end prospects for Donovan, Gray, and Contreras, don't at least 1 or 2 have to work out? Then if 2 or 3 of our current top 7 work out, then you have a core. By working out, I mean a minimum level of 2-3 WAR player consistently.
And trades are now judged by BTV values??
If Cards prospects produce 0 value going forward and Sonny wins 16games on a WS Boston team next season what’s the BTV???

if you look under the "About" drop down menu, you can read up on how they put a value on major and minor league players.
Of 996 trades they have reviewed since 996, their model would have said that 931 of them were close enough in value that they would be accepted, so that's 93.5%.
Their methodology for valuing players and comparing values offered in trades isn't random if it is agreeing with real world trades 93.5% of the time.
