Dale Earnhardt Jr.

The devastating concussion and balance/vision impairment issues that Earnhardt suffered due to multiple crashes last season took the NASCAR icon out of the driver's seat at mid-season in 2016. He only completed 18 of the 36 events before being sidelined. It was a season lost for the driver of the No. 88 Chevrolet. However, the good news is that Earnhardt is much better and has received medical clearance to race again as of early December. Before the injury the veteran driver had been performing at his highest level in years with great campaigns in 2014 and 2015. While all would appear to be all right physically with Earnhardt, we'd be a bit leery about building a fantasy race team around him, with Earnhardt being the anchor driver. As it goes with drivers and concussion histories, all it takes is another major wreck to put your driver on the sidelines for multiple races.
