his wRC+ went from 115 to 99. He didn't improve. Hard hit rate is 1 measure, not some be all end all thing that indicates significant improvement. He's not a power hitter, never will be, so he should stop trying to be one and get back to doing what he was successful at, which is hitting from line to line. If he hits the ball harder while doing so, great! Might mean a few extra base hits over singles, but he has got to get this idea out of his head that he needs to be a power hitter. It broke his approach and made him less valuable as a hitter
