I don't feel like Sano being so far down on this list is fair. Especially when we all know you are gonna put a couple A ball players 1 and 2 who have just as much, if not more of a chance of washing out. Sano is top 5 IMO on this team. They will still rise and fall with Sano and Buxton the next few years.
One difference between Buxton and Sano's hitting that I have seen with my eyes. When Sano came up, he was patient, didn't swing at junk, walked a bunch, then hammered pitches when he was thrown hittable strikes. He lost that somewhere along the line, but his OBP and walk rate in the minors suggest he is capable of that again.
Buxton never had any patience(at the ML level anyway) looked lost, guessed almost 100% of the time. He is still looks like a high school hitter. No polish whatsoever.
I feel like Sano will be back if he can get himself in shape and his head screwed on straight. Almost seems like it is mostly mental with this guy, hopefully he has grown up. I guess I don't ever feel like Buxton will be the type of patient hitter Sano CAN be. He can still be a good hitter, but he is gonna have to do it by making good contact and using his legs.
