First look at fantasy football in NFL Week 4: Bigger role in David Montgomery's future

Chicago Bears head coach Matt Nagy told reporters after the stunning, come-from-behind Week 3 win over the Atlanta Falcons he did not know whether Nick Foles or Mitchell Trubisky would start at quarterback in Week 4 against the Indianapolis Colts. OK, perhaps he actually believes this, but for fantasy purposes, it might not matter. Yes, it is a big deal that Nagy pulled a struggling Trubisky and Foles tossed a trio of fourth-quarter touchdown passes, but the dispiriting Tarik Cohen injury plays a larger role in fantasy football.
