BC improved with their additions (better coaching and added key components to their o). If I were them I'd look at a better backup qb and kicker and they could be fighting for a playoff spot.
The Riders on the other hand lost a good chunk of their core in free agency, retirements, and opting out due to Covid. If you remember back in 2019, that one DB spot cost them some games until LJ McCray stepped in.
I think the Riders will be fine. Just alot of guys who haven't played together before which is where you saw breakdowns in their linebacker coverage depth and busted coverages in the second half.
Thankfully their defense still has alot of veteran presence so can see then sorting it out. Nobody expected mistake free football from any club one week in off a nearly two year hiatus and no preseason games
Good news is they won. Picking off early wins whether ugly or not goes along way to the pecking order in the playoffs. In a shortened season, these wins go along way
