It's a great position to be in. You always want talent coming down the pipeline to fill in the gaps and help if players get hurt/don't progress as expected.
As you say, a couple guys might bust. But even if we hit on one or two of them, we are pretty much set for years to come - hopefully, the busts are more on the position side of things than the pitching side.
I think 2021's offseason is shaping up to be a critical one for the Blue Jays. We are going to have a TON of space and I think we need one more starting pitcher and one proven position player to really become contenders for a WS. It will be interesting how free agency shakes out with the fallout of a shortened 2020 season and the possibility of a lockout. But I think Mookie Betts is the guy you go all-in for. He's basically a perfect fit for this team from every standpoint (age, position, hitting, leadership, and he's got a long history in the AL East). Then you see how the pitching market unfolds and try to get a solid middle of the rotation guy to add to Ryu and, hopefully, Pearson.
Then you ride that wave for the next couple seasons and keep adding talent as they develop. Which is much better from a sustainability perspective than trading for veterans.
