The reality is that we don't have a single Canadian worth being a full time starter on defense right now.
What we have is a stockpile of Canadians who can take a limited and controlled amount of reps in order to manage the ratio via committee.
I'm sure we'll see Newman at WILL, Hurl at MAC, Thomas at DT, Sherman at S, Bucknor and Jones at the corner all taking meaningful reps this year. But not a single one of them will likely be asked (outside of MAYBE Bucknor) to be an every down player.
