would be my three.
Alexander replacing Hecht was a huge move for us.
Bryant is the best tackle in the CFL
Collaros because hey, 17-2 as our starter.
Not that I'd be happy to lose him but if Couture left, I believe Speller is a pending FA. (He did play C for all three 2019 playoff games).
Harris-Want him back of course but in theory Oliveria/Augustine would work.
