Though the Colts visit the Texans in Week 6 and the Texans are vulnerable against the run, allowing 132.2 yards per game, 25th-most in the league, running back Trent Richardson isn't such a great play in Fantasy. The Colts went a different direction with their backfield platoon in Week 5, giving Ahmad Bradshaw more reps than Richardson for the first time in three games, which puts Richardson's relevance to Fantasy owners in question.
To put it bluntly, he's inefficient, picking up yardage in small increments. Regardless of the matchup, he needs bunches of carries to get anywhere, and it's not so clear right now that he'll have them.
The upside is minimal -- in standard CBSSports.com leagues, Richardson has only once scored double-digit Fantasy points this season -- so you don't stand to lose much by benching him. Jamey Eisenberg and Dave Richard barely have Richardson within their top 40 running backs for this week.
