From the video

Start of the week is Demario Douglas. Detroit's bad against slot receivers... Douglas is on an absolute heater right now. He has emerged as the wide receiver one with AJ Brown being hurt... He is 16.5 fantasy points in four of his last five games... he has the highest yards per route run against man... Detroit is giving it the second most schedule adjusted fantasy points per game to slot wide receivers... he's been kind of on fire.
STACKED’s take
Emerged as WR1 with injuries; 16.5 PPG in 4 of 5 games vs. slot-vulnerable Lions
Super special secret start of the week with multiple converging advantages: emerged as WR1 with AJ Brown and Romeo Doubs injured; runs 83% of routes from slot where Detroit is second-worst in schedule-adjusted fantasy points allowed; has highest yards per route run (4.6) and separation score against man coverage; posted 16.5 fantasy points in four of last five games; recorded 9 targets last week for 102 yards; third overall in slot assignment; 11 deep targets (13th among WRs) despite slot role; Detroit allows bottom-six deep yards per game (49 per game). Josh McDaniel's slot role historically valuable; Douglas is a man-coverage killer with only JSN higher in yards per route run against man over two years.
