Colts running back Donald Brown is a risky play Week 17 against the Jaguars.

Jacksonville presents a good matchup for Brown. The team has allowed opposing running backs to average 19.20 Fantasy points per game. Through 15 games, the team has allowed 18 rushing touchdowns. The team also allows running backs to rush for an average of 112 yards per game. The first time the teams met this season, Brown carried just three times for 65 yards. 

The problem is, Brown isn't a reliable runner. Though he's shown more ability than Trent Richardson, the team continues to rely on Richardson as the primary workhorse. Brown has had good games with Richardson, but it's just too difficult to rely on him as a Fantasy starter. He has decent upside, but the risk outweighs the rewards, even when the matchup is great.
