Should I drop Kenneth Dixon or Keep him in a dynasty league?
Keep him unless there is someone else worthwhile to pick up. Or are your evaluating for a roster cut date?
Roster Cut and Eric Ebron is available
Who are your other TEs, and RBs?
Reed, Burton, and Jonnu Smith
I’d keep him and see how things shake out. It’s entirely possible he becomes the lead back, or at least gets in a timeshare with Collins.
I’d be fine with dropping for Ebron.
