STACKED’s take
Flowers sees elite usage shift and is trending up in dynasty rankings
Matt Harmon notes a significant shift in Zay Flowers' usage, with his slot snap rate increasing to 45% and backfield usage to 13%, while route participation from the slot has risen to 66%. Flowers is being effectively schemed into layup opportunities, with 335 of his 352 receiving yards coming against non-cornerbacks. His route tree has evolved to feature a 29% slant and 21% dig rate, where he has been excellent, losing only two charted reps. He maintains a 92% success rate versus man coverage and is on pace for 1,500 receiving yards. Harmon plans to move him up in dynasty rankings due to his elite talent, connection with Lamar Jackson, and a favorable upcoming schedule against Atlanta, Cleveland, Cincinnati, and Buffalo.
