I'm reluctant to speak for Hosken, but I took his post to mean, if you are going to cite something (like RF) as the best evaluation tool to use, it would help if you would provide the data. "I prefer RF, here's why, and here's Adrianza's minor league RFs." You might then go on to compare that to some relevant examples, to put the data in context. In other words...I don't think it's on us to "look it up."
