I'll repeat myself from the middle in the 2016 season. JBJ has a tendency to over swing, presumably to add power when he makes contact. When he does that, his swing gets longer and he tends to loop it, perhaps to add loft to the ball. The problem with that approach is JBJ has difficulty making regular contact when going with the longer swing. In my opinion, JBJ should work on a compact and level swing. He could improve his contact rate doing that and perhaps he would lose a little power, but he has enough to still hit home runs while making that change. Failure for him to make a change will relegate him to the same type of performance as this year or perhaps even worse, since the pitchers seem to have him figured out. I like the kid and think he has additional upside, but he and the coaches need to work to make changes during the off season.
