Nice depth positions. I’m not that high on Mayala but maybe this signals they don’t go for REC early in the draft as believed by some. Richards is still young & didn’t fit in with the Argos who have the best OL in the league & replaces St John. Steward is a veteran who likely provides depth. I believe both the OL have played @ OT & inside.
I don’t see any of these starting but will battle for backup spots. Can’t hurt to have them in camp.
