That is pretty much how the baseball world worked, and failed, for decades before smart people supposedly figured out better ways to do things. The age old "Scouts vs. some vague thing Kyle started saying" debate. No, the "people who have seen him play a weekend series say it is so" and "I read a vague quote about it 2 years ago and assume both that it was accurate and that it is still true". But Kyle isn't basing his argument off anything. He's just decided that he doesn't want Almora's defense to be good, so he's making that declaration. Even "saw him play a weekend series" is more valid than whatever Kyle is doing.
