I'd say maybe 2-3, but I get and agree with your point. I also think it higlights why it's important to understand the dividing line that exists as we approach this draft.
We can still find talent beyond the top 10 picks in this draft. Now, the odds of finding elite talent go down considerably, and it's exponentially more difficult to find players who will provide more immediate help, but there will be some intriguing options there.
A lot depends on where we pick. For example Lundell at 10 could be a player who steps in next season, or maybe 2021. He's also a guy who wouldn't necessarily be a poor choice to start in a middle or bottom six role. But he's not almost certainly not going to be there at 15 and beyond.
At 15 you start getting into the players who are a little further out, and have some combination of lower ceilings, or lower percentages of reaching those ceilings. But they aren't "bad" prospects by any stretch.
So at at 15 and beyond, you start talking about names like Holloway, Zary, Mysak, etc. etc. And each of them has certain pros and cons to their game.
But wherever our pick(s) fall, we're probably looking at a depth scenario, rather than focusing on a pure-skill, highlight reel producing machine. With multiple picks, we might even go for a balance of the two. But I'm not sure there is an immediate savior on the horizon. And frankly, I'm not sure the Rangers need there to be one.
