That's just it, though. Referencing only Baseball America and criticizing their rankings is being very myopic and extreme in prospecting views. There are a wealth of highly respected prospect writers out there, and reading on all of them is vital, as is seeing some games in person. Milb.tv is a wonderful service, allowing you to pick a game or two to watch whenever you'd like. I've watched Hernandez pitch, and I don't have the same doom and gloom of Sickels' analysis, but I don't see anything that you'd want going every 5 days right now. He would make a solid LOOGY, but his fastball straightens out fast, so the second time through a lineup is when he gets teed off on. Kevin Goldstein said via Twitter that the Twins got good roster filler pieces but very little upside in the deal. That's what most are upset about is that Liriano should have netted something with upside, unless the organization feels it can compete in 2013 or 2014 and LOOGY guys and Rafael Belliard types are going to be of value. Taking one high-upside (and likely equally high-risk) prospect in a deal for Liriano would have fit more with the idea that the team is at least looking toward the future. Heck, look at the haul that the Astros have picked up. None of the guys they've acquired in their deals this year have been high-ceiling guys, but that's okay as they picked up a couple guys like that last season. Now they have the makings of a very solid infield and outfield in their minor leagues with a very high upside catcher as well, all acquired in the last 12 months, not to mention essentially an entire pitching staff. That rebuilding has been very well done, and I think Twins fans have some right to wonder why their pieces weren't spun into a future roster in a similar manner. Baseball America is a solid tool, but to base anything off of ranking numbers is completely ignorant of the process. Jim Callis of Baseball America has said it before that the reason you do lists isn't because you feel there's an actual pecking order. It's because it sells and appeals to the lowest common denominator of reader. His hope is always that people will read further into the scouting reports that accompany such lists to understand what BA truly felt about a guy, potential and limitations. Reading through the write ups done on Brandon Wood always indicated a high degree of risk based on his swing and miss tendencies, for instance, but the potential stardom was through the roof because of the raw power. Prospectors are always working to improve their craft as well, so criticizing a process from 1998 would not include most of those working in the industry now as the old guard has given way to a new brand of scout/stat/evaluation hybrid that is constantly seeking to improve predictability and accuracy of reports.
