There are several drivers who took a big step forward this year. It's just about impossible to pick one and say he or she is the most improved. I could make an argument for any of the following: Justin Grant, Wes McIntyre, Logan Jarrett, Chase Stockon, Josh Cunningham, Kevin Thomas Jr., AJ Hopkins, Coleman Gulick or Logan Hupp just to name a few. I'm sure there are more I could add if I sat down and thought about it.
