Interesting article about Chad Kelly in The Athletic. https://theathletic.com/3642208/2022/09/30/chad-kelly-cfl-toronto-argonauts/ (paywall)
The long and the short of it is he's a backup up in Toronto and still blames everyone else for his problems, his dad worked night shift, his uncle cast a big shadow. Even when he blames himself for something he talks about himself in the third person.
If he was half as good as his hype he'd be setting the CFL on fire. Meanwhile he's only attempted 4 passes in 13 games.
