5 to 10 years????? The 2016-17 Leafs made the playoffs with a pretty young team and a weak d-corp. Once Nylander, Marner, and Matthews came to the team, they started playing better. Blues have 5 legitimate forwards right now, 8 if you count guys like Bolduc, Snuggerud, and Dvorsky, so assuming the band stays together, you have a really good offensive top 9. Keep in mind the Leafs weren't this defensive dynamo with their group of forwards and their defense was pretty bad. In 2 years, the Blues will absolutely have a better team than that Leafs team AND idk if the western conference is going to get stronger any time soon. We have goaltending depth to withstand some injuries, and some ok defenseman who can come up in case of injury, and enough forward depth right now to at least be competitive in the division, maybe not league wide. To say you don't think they'll be a serious playoff team for 5-10 years is a bit ridiculous. I mean we gave the Avs their hardest test during their cup run with the same group of defenseman, though I will grant you we are not as responsible on the forward side.
