| former MikeN in Ottawa here.
Ceresna came into the CFL in 2017 with the Ottawa RedBlacks and appeared to be a young player with a bright future. There were various times he impressed and then, late in that year, Ottawa traded him to Edmonton and I am not sure it was ever made clear why. Last year for Edmonton, he had 32 tackles, 8 sacks and one forced fumble. In 14 games for Ottawa in 2017, he had 18 tackles and 2 sacks.
He is probably a little light to play DT in the NFL. My personal feeling is I expected more production from him. I always was left the feeling of wanting more. I think he has talent but I do not think that talent is transferable to the NFL. At best, perhaps a depth player or a PS guy.
I do not see him as a possible future starter.
