I haven't taken enough of a look at what other teams drafting has looked like in that stretch to have that detailed of an opinion on it. I took a quick look at a few teams that I think people tend to think highly of in terms of drafting developing (specifically the Rays, Yankees, and Dodgers) and they don't look any better.
The Rays have drafted two players in that span with a higher bWAR than Biggio (Lowe and McLanahan).
The Dodgers have Smith and Gonsolin.
The Yankees have no one.
Who else is viewed as a top draft/develop team around the league? Atlanta has Michael Harris (and I'll throw in Strider too, since he's obviously an elite pitcher).
I picked a few other teams at random:
The Twins have none.
The Phillies have none.
The Royals have Singer and Witt.
The Brewers have Burnes.
The D-Backs have Varsho (and I'll give them Carroll based on last year).
The Astros have Pena.
So... I don't know. Biggio would be a "relative success story" on literally every team in the league and the best player drafted and developed by a lot of teams. No one has more than a couple impact players in that span.
I think you're trying to compare the Jays to a benchmark that doesn't exist.
