The Chiefs had what, 3 or 4 possessions in the 1st half? IMO, the defense didn't really frustrate them, they simply played deep and hoped a dropped pass, missed blocking assignment, penalty, etc... would cause them to punt.
The Chiefs being mistake-free is probably a lot easier when they have the easiest passes to complete. Option routes all day. They were upset on just ONE play where Kelce turned the wrong way - because the defense is predictable and pretty much a lay-up for those option routes.
Obviously we're not giving up 33 points to every team but if we continue to run a conservative defense with no exotic coverages and disguises, we're gonna elevate the floor for a TON of teams.
