He had one decent year year in 2019 with the Lions. He never played a full season with any CFL team. Many other National players were far, far superior to him. "Good level of skill for a Natl." is a stretch. My feeling is that he was less than average at best. Don't mean to be overly harsh but I never understood the hype about him.
Durant was a physically gifted receiver, who dropped in the draft because of poor interviews and questions about his attitude or motivation.
Calgary was bringing him along slowly, but in 2019 he finally lived up to potential in BC. Why he couldn't sustain that, or his proneness to injury are questions beyond my ken.
As to the hype, the only other receiver of note in that draft class was Demski. The Bombers passed on Durant in favour of the luminous talent of Addison Richards.
I think it is fair to characterize Durant's career as disappointing, but the kid had all the tools to be a top level receiver.
