Right. To acquire stars with prospects requires that that team have accumulated those prospects to trade in the first place, most likely via the draft. As with all commodities, there are two types of values: use value and exchange value. And then that’s compounded by a temporal dimension. “Draft(ing) well” requires a balance between the two types of value that is aligned with your current set of competitive goals. Maximizing across those dimensions subject to multiple constraints is the whole point of Ottoneu.
For example, if I drafted a $1 Royce Lewis last year and then trade him midseason for a $20 (or whatever) Zack Greinke with the goal of winning that year, then I’ve drafted well (even if I cut Greinke in the off-season). Or at least better than the guy who spent his $1 on Derek Holland instead of a prospect and then complains about loan trades year-after-year where he consistently finishes in 5th place. Now Holland had a very good year last year and yielded a high ROI, but I’d still rather have the prospect who can net me a half-season of Greinke midseason.
