Even college guys who breeze thru the minors typically need a full season of development, putting his ETA at 2027. But that's usually top of the draft elite ready talent. If he hits, he probably still needs 2-3 years to cook min.
Lets also never forgot. You can trade guys. If you knew your outfield was set for the next 10 years, and you knew a prospect was going to be stud you'd still draft him 100% of the time because you can always trade guys. If you see something in a guy, you like him, and you think you can develop him you are NEVER looking at current needs of the big league team when making most trades.
