Again, you're getting caught up in hype an expectations. You have to realize that there is a very high bust rate on EVERY prospect, including Bundy, until they produce in the ML. Don't get caught up in that whole, this player is a number 10 prospect, or top 3 prospect in baseball. It means nothing until they deliver on that promise at the ML level. Yes, educated guesses say he will be a great ML pitcher, but that's all it is until he actually does it.
When they draft players they are always thinking, I'm pretty sure this guy is going to help our ML team in some way, and in many cases they are considering that floor you are thinking about now. This guy could be an ace, but at worst case should be a solid 4th starter, I'm sure that exact line popped up in 2009.
There aren't 30 no. 1 slots, there are slots 1-30 in the first round, and a "good team" is another way of saying first division, it's just semantics. BMat can be a solid #3 on a 1st division team, hopefully slotted behind an Ace and a #1/2 type. I think he ends up having a better year than Arrieta, and still think Jake is our Josh Bard. Serviceable in the rotation, but could be a standout closer.
It's natural to have high expectations for highly drafted players, that's actually very normal, not just me front offices as well. Remember when Matt Wieters was being labelled a bust? I actually like to think I have realistic expectations. I don't expect Bundy to dominate once he comes to the bigs. But will I be disappointed, if he ends up a back-of-the-rotation pitcher, absolutely. No reason why you should shoot the bar too low, just the same way you shouldn't shoot unrealistically high.
On that last point, you are misinterpreting what I'm saying. What I'm saying is each team has a number one pitcher=so there are likewise 30 #1, 30 #2, 30 #3, 30 #4, 30 #50.
