Remember the deep throw to Crabs in the @NO game? Kap rolled one direction and threw across the field. This is not a throw many QBs can make. Normally, when a QB rolls out in one direction, the field is cut in half and any backside routes are no longer target-able due to lack of arm strength.
Here is a play that results in a large gain where Kap showed off his arm strength to target a route on the other side of the field (vs ARI). The Crabs catch in NO was a broken play, this play (link) vs ARI is designed.

With the 49ers running a couple flood concepts by first faking the stretch left run on their first drive, the 49ers come back on the second drive and try to catch MIN napping.
I think it's Cover3.
Fake the stretch run left.
Rollout right, but look backside, hoping the safety rolls coverage to the strong side (same side Kap rolled to). The safety is alert and is able to provide double coverage on VD. Kap targets VD anyway, nothing else was open.
Some have stated VD should have kept running hard. I have a feeling Kap overthrew VD on purpose. This was a bit of a forced throw. Good job by the safety not falling for the misdirection.
