Burfict out need LB help

As always thanks for the advice. With burfict out for the championship week I need to pick someone up. Its a tackle heavy league and im looking for a high floor guy, who do you think the best option out of your waiver adds (Moore, Irvin, Spaight, Ryan) would be, or would you go with Vincent Rey? Im not sure how the hamstring injury effects him though

Sio Moore is the safest play there. Dansby if he's available is a good option as well.
