I also agree on Soto and Lotzkar they have that top of the line talent, now what they do with it from here out is the question. I really like Soto's chances as I have stated ad nauseum so I won't go into it again. Lotzkar who knows what with the injury and the simple fact he is so young and still far away developmentally. But I have the highest of hopes for them both obviously.
On Heisey, I agree he has no major weaknesses. However that's a double edged sword because I also don't believe he has any major strengths. What I mean by that is I think he's got average all around talent and very good intangibles. His only major tool is speed and I don't think it's quite at a Freel level, although as Doug stated he uses his speed better than Freel does. I think his ceiling is as a poor man's Denorfia, which makes him a real good 5th OF/pr/late inning defender who should give you a solid AB and won't be a complete stiff up there.
The only problem I have with the list is that Francisco is still on it. The hurdle he has before him is a monstrous one and I would venture to guess that less than 1% of ballplayers with that specific issue never even make it to AAA let alone to the bigs. Yes he has some serious talent and he has time but does he have the patience and discipline to make his weakness just palatable, I don't know but I wouldn't bet on it. Just my 2 cents but I have mostly written him off as nothing more than trade bait. Here's to hoping he proves me wrong.
