I really could have built a case for any order between 17-25 so honestly, there are little nuances here that have them in the order I put them in vs anyone is dead wrong for having a different opinion.
As you said earlier, this is where the depth of the system shows. We have guys still with upside in this range and they typically would have been in the 12-18 range in prior lists.
Would I prefer a plus change to the curve, perhaps, but I will say that although Well's change is a little to firm and lack great depth, for some reason batters struggle with the pitch from what I've seen. I was really looking forward to seeing him in AAA where the cameras are much better for assessing pitches.
I felt a "rude awakening" every time he hit it solidly - especially all of the doubles with his gimpy legs. Even with his injuries, he hustled down the line every time. So I will still not expect anything from him, but if he continues his "lucky streak", I will be amazed.
I could easily have built a case for Rom to be above Wells, but this is where having success at AA gives Wells a slight nod in my opinion. Rom certainly could be much higher next year. They're basically the same type of prospect in my eyes with Rom having a slightly high ceiling because there could still be some major improvement due to his age.
