"No, but trading for prospects has less of a success rate for most teams than just developing a farm from within."
That doesn't even make sense. So Wheeler has a higher likelihood of failure because we traded for him instead of drafting him?
"It most likely won't even contribute to a dynasty."
Name me any team that had extended success without bringing up young players from the minors. And isn't the late 90s yankee model considered the model everyone should strive for? young top talent with talented vets.
"People feel smart advocating trading everyone for prospects, but at some point you actually need players who are good now"
Now i don't want good players? Where are you inferring this from? I'm throwing down a plan of strategy here that i think we need to enact for long term success. If you have a better idea, let me know. Of course they should sign players also that can put us over the top.
