The Twins didn't really have a choice in buying on SP. Their system was pretty bereft of SP talent for the last few years as only Gibson has turned into something. They have some higher ceiling talent at the lower levels and now have some decent talent moving into the upper levels, but it takes 5 starters and as is true with pitching prospects, many never make it. They had to buy SP. I tend to think it would have been better served to go out and get the top one (say Anibel Sanchez or Max Scherzer), but when you need to get several starters, going out and getting guys like Hughes, Nolasco, and Santana make sense given that they just didn't need one guy, they needed a rotation. This was probably the best means to get one. I personally tend to think that stolen bases are overrated, though going from 1st to 3rd or even 1st/2nd to home on a base hit is valuable. You are accurate in going for high OBP guys, but truthfully, that can be taught to some extent. Both Vargas and Sano have done a pretty decent job of that in the minors. Arcia, while needing some work there, was not terrible either.
