While I do let the computer do more of the draft in 14, I really like the new system of developing players over previous versions, but I do agree that there should be more higher potential players in the draft to begin with, like what "markprior22" said 2 posts below this one. I've noticed the potentials of some players improving over their years in the minors and I also like how there's no big potential ratings dropoff. The players end up fine in the Majors.
Edit: One thing that is unrealistic is the amount of first round picks actually ending up in the Majors. Almost all of the players picked in the first round reach the majors and play for a while. Scroll through the drafts
here and see how many players from the first round did not make the majors.
Edit 2: Changed stuff
