Yeah, okay, I was trying to play along with this like without treating you like you're dumb, but you are making that more and more difficult with each post. A player's minor-league performance, especially high-minors, can be reliably translated into a Major League Equivalent. That MLE is just as predictive of that player's future stats as a major league performance would be. A .260/320/400 MLE is predictively equivalent to a 260/320/400 MLB stat line. Where most prospects flame out is that their MLEs are close, but not quite, up to par. The teams hope they will continue to improve and they don't. Take Felix Pie. At age 21 in 2001, he put up a .283/.341/.451 line at Iowa. Plugging that into the handy online MLE calculator, that is the equivalent of a 230/274/352 line in the majors. Despite that, the Cubs called him up in 2002, hoping he'd continue to improve because of his age. He didn't, posting a 215/271/333 line, eerily similar to his MLE the year before. He improved a small amount but mostly stagnated and became a .249/.298/.374 career hitter. Again: It's a long-proven sabermetric tenant that properly-adjusted MiLB stats are just as predictive as MLB stats. The problem is that most people overestimate how predictive MLB stats are (even established players are pretty volatile) and they underestimate how harsh MLE adjustments can be. The idea that we have to just throw up our hands and pretend like we have no idea what to expect from these guys is lazy and wrong. Very nice description of MLE, including an example. A+
