Friedman isn't home grown, they identified, targeted and acquired. Their # 1 payer Mookie Betts (pre-Ohtani) was acquired via the use of specs. This year's mid season farm system rankings had the Dodgers 6th, the Blue Jays 26th. The Dodgers just sent specs to acquire Glasnow and they won't miss a beat in terms of the pipeline of prospects on the way.
Using the amount of home grown players on the roster as a comparison is not an equitable metric by which to measure sustained and future success. Assuming you are saying that the Jays and Dodgers are somewhat equal due to the amount of homegrown players.
The Dodgers also lost Urias a top tier SP to off field issues as they did Bauer, albeit he was a FA.
