Trey Williams and Nick Williams are a couple of intriguing players. Their respective positions are 3rd and CF/RF. Before the start of the season, they were both viewed as 1st rounders, Trey Williams even as high as a top-10er. Between then and now, not sure what, but something went wrong. Now both are viewed supplemental rounders, Baseball America even ranking them as low as #99 and #100.
I personally feel like it'd be a stretch to draft them with the #47 pick, even given their high potential. They are just a little too raw for my liking. At this point, Daniel Robertson, Corey Seager, DJ Davis, and Fernando Perez would be similarly good picks there (in my opinion of course).
