Juan Uribe, him of the career .298 OBP?
You just managed to make a completely incorrect point comparing Moustakas who is a by and by free swinger (3.85 P/PA) to WMB, who has decent plate discipline (4.18 P/PA, right above league average) but has problems with a specific pitch in a specific part of the strike zone. WMB also showed significant improvement after coming back from the minors. You can't base an analysis of what WMB will be, or is, based on a 300 PA sample. That is ridiculous. If it was one of your s***** binky players you'd be clamoring for patience, but since it's a guy with actual talent, well then, f*** him.
Then right after that you manage to contradict your own point by saying you could "stand" two guys who are just as bad at getting on base, but either feature a worse or similar glove, and less offensive upside. Are you serious with this?
Please stop.
