The fans don't need to worry about where the team ends up. There are no guarantees in any of this. What the fans should worry about is that the management running the team is competent enough in their jobs to assemble a roster that can compete for the cup. Even if they assemble a roster that can compete for the cup, there is no guarantees that they are going to win it. A step always seems to be glossed over in this thought process, where "higher chances" becomes "absolute certainty" which drives the expectations out of whack.
If the Leafs draft 7th, they draft 7th, if they draft 1st, they draft 1st. The management team will have to decide what to do based on which scenario they are presented with.
Everyone focuses on "I want Connor McDavid, I want Auston Matthews" as if that will change the teams fortunes just by virtue of them being a great player. What I would like, as a fan, is if the team that I cheer for isn't the laughingstock of the NHL, and I think they have made good strides towards getting there. When I say laughingstock, I don't necessarily mean by their play on the ice, but rather the manner in which the management and the team conduct themselves. I would like to trust that the management team that is employed by the team that I cheer for is going to make smart, informed decisions and develop a course of action that will produce a product on the ice that one can take satisfaction in watching. Occasionally they may make a mistake. That happens to even the best management teams. Overall however, I hope that they will make consistent decisions that will drive the team to their goal.
That's why as I fans, I don't feel that we need to be concerned about where the Leafs draft. We would need to be concerned if the management team got told they aren't drafting in the top 3 and they threw their hands up in the air and went "well that's it, we're done. Pack it in people, this rebuild is a bust." which is not what I think will happen. We should just enjoy the ride, wait and see what happens, and watch how the team reacts to the results.
