Riders blow it...Dorsey shoulda started

The Argos lose their QB and running back, yet still beat the Riders on the road. The big plays killed the Riders and you got to give the Argos credit. I do think the Riders should have started Dorsey again, he provided a spark versus the Lions and KK was nowhere today.

Why does it seem like the Riders can't quite recover a critical fumble this year? (onside kick aside.)
