I'm in a 12 team standard league. We are limited to 5 roster spots max at RB. I have Najee Harris, Ronald Jones, Ty'Son Williams, James Conner and Trey Sermon. I was possibly going to drop Jones for Mitchell but Jones was just named the starter for this week. It's between him, Conner and Sermon. Am I better off dropping Conner to get Mitchell and lock up the SF backfield assuming McHasty is not the guy or just stand pat and see if Sermon becomes the guy and hold my shares in the other backfields? Thanks in advance for any comments.
