Spencer Ware, RB
When it comes to underappreciated running backs, the Kansas City Chiefs absolutely own the category with Jamaal Charles. Charles was arguably the single most dynamic offensive weapon in the game when he was healthy and his robust 5.5 yards/carry average with the Chiefs proves just how effective he was even without any threat of a passing game for much of his career.
We've written a lot about Jamaal Charles over the years and there's more to come when Hall of Fame arguments are ready to be made. That's why we're actually glossing over Charles in this instance in order to point to someone who was always there waiting in the wings later in Charles' career: Spencer Ware.
Ware came to the Chiefs as a former undrafted free agent wtih the Seattle Seahawks in 2015. Ware hadn't even played an official snap the year before, but along with Charcandrick West, Ware helped the Chiefs employ a productive backfield while Charles was out in 2015.
In 2016, Ware stepped up as a lead back when the Chiefs needed him in the wake of further injuries with a team-leading 921 rushing yards and 1,368 yards from scrimmage that season—both career marks for Ware. In 2017, he would sit out the season due to injury but he returned in 2018 to back up Kareem Hunt. Ware would end his Chiefs (and NFL) career with just three appearances in 2019.
For a player who once led the Chiefs in rushing yards, Ware deserves a bit more respect than he likely gets. He's a player who fought long odds to even make it to the NFL but he came out on top with a respectable career and several memorable moments for a team beginning to form a dynasty.
