Maybe it is just me, but it would take more than just one prospect rated 25th. That is in the Berrios/Stewart range. With Dozier, I think we are starting to know what we can expect. Very good defense, 20-20+ potential, a guy that gets on base, etc that plays a scarce position. Many prospects in that range may simply "project" as having a simlar trajectory as Dozier and frankly, a good chunk of them won't hit that projection. Some may never stick in the big leagues and some may end up being bench players.
Yeah, as I said in another thread, it all depends on the player. "Top 25" is basically code for "elite prospect". If it's near the bottom of that scale, it will require another guy with upside.
For example, I'd trade Dozier straight-up for a non-injured Sano (and obviously Buxton). I wouldn't trade Dozier straight-up for Alex Meyer or Kohl Stewart.
