DeVone Claybrooks would seem to be the more logical choice for the Stamps. Claybrooks has previously mentioned that he would be fine just being a DL coach.
Should the Als somehow hire Thorpe as their DC, they could always reshuffle Barron Miles to be a position coach.
John Bowman has publicly expressed interest in directing the Als DL but with cap, it is hard to bring in inexperienced coaches.
Sammy Gahagan who supposedly was the Special Assistant to the GM/Scout in 2021 was named Director of US Scouting in Edmonton. I say supposedly because he was never listed on the team website. The one time I heard him interviewed, he was not even talking about the Als. The CFL story he told was finding a player for Chris Jones when he was a scout for the Riders.
