1. WR Zay Flowers
Flowers' performance on Sunday afternoon is going to be feed sports talk radio for, at a minimum, the next two weeks alone. The box score stats look good: the rookie wide receiver had five catches on eight targets for 115 yards and the Ravens' only touchdown. But Flowers' day will be remembered for the handful of crucial mistakes he made in the final quarter that caused the game to slip away from Baltimore: mainly, the taunting penalty on a 54-yard completion, and the goal line fumble out of the end zone. He also then reportedly cut his hand on the sideline in a moment of frustration immediately after. According to NFL's Next Gen Stats, that fumble cut the Ravens' win probability in half, dropping from 28% to 13%. Flowers has a bright future ahead of him – he led the team in receiving yards this season (858) – but there's no doubt he had a rough day at the wrong time.
