When he threw snowballs before the Broncos game at Arrowhead, Demarcus definitely was more Jackson than Patrick as far as form goes.
As far as football goes, the most impressive thing about Demarcus was how many iconic Mahomes plays he was a part of, despite being a mid WR. Remarkable highlight reel (courtesy of Mahomes mostly), unremarkable wideout. But that is enough to remember fondly.
