10. Jimmy Butler
2014-2015 Most Improved Player Award winner Jimmy Butler was well-deserving of that award after an excellent campaign, which saw the 25-year old pick up the first All-Star appearance of his career. Butler served his team well on both ends of the floor, averaging 20.0 points, 5.8 rebounds, 3.3 assists, and 1.8 steals on 46.2% shooting from the floor, and 37.8% from beyond the arc. One of the best two way players in the NBA right now, Butler can guard almost any guard or small forward in the league, and on some nights is able to completely shut down even the most potent offensive player. 2015-2016 saw him get even better as he put up 20.9 points, 5.3 rebounds and 4.8 assists on 46 percent from the field with yet another All-Star selection. Jimmy Butler is just getting started and could very well end up in the top 6 of this list if things go according to plan. I can’t wait to see how this dude’s career plays out – he is something special.
