check out Keith Law's view on Brett Wallace and remember Law was one of Wallace's bigggest supporters, he ranked him in the top 15 or something ridiculous like that in his midseason rankings.
The way Wallace’s rise to the majors has stalled out has been a hot topic among scouts this winter, since at the time he was drafted the debate was over whether he could play any position well enough to keep him off DH, not whether he’d hit. But the new consensus is that Wallace can’t cover the inner half because he doesn’t fully rotate his back side through his swing, ceding the inside part of the plate to the pitcher, and that it’s not fixable. If anyone can help him, it’s new hitting coach Mike Barnett, who was hitting coach in Toronto while I was in the front office … but the industry has officially jumped off the Wallace bandwagon.
Alex jumped off a sinking ship just in time, if you wait two more months and let everyone in baseball see his 60:5 K:BB ratio(or something awful like that) you couldn't get a bag of balls for him, let alone an Anthony Gose.
