Panthers HC Frank Reich told his players Monday that he's handing over play-calling duties to OC Thomas Brown, NFL Network reports. The move comes as Carolina heads into a Week 7 bye. That should help with the transition, which has been rumored to be on the way since before this season started. Brown was a trendy head-coaching candidate last offseason but is in his first year as an NFL OC. So it's tough to know what to expect here. Brown did spend his first three NFL coaching seasons on Sean McVay's offensive staff, though. And it's hard to imagine the Panthers getting much less efficient on offense. They sit third-worst so far at 4.4 yards per play and third-worst in net yards per pass attempt. We'll see whether the switch produces any noticeable boost to offensive efficiency and/or fantasy upside.
