Sure, 14-9 is way better than 21-9, but being down 12 points is hardly insurmountable, especially for an offense like KC's (which is not to say that Reid didn't screw up, but it was not the reason they lost). And running the ball more was not the missed opportunity that would have netted them the win. What they needed was an OL that actually protected Mahomes and gave him more than 1 second to throw. They eye test showed it, that "scrambling" stat showed it. For a prolific offense that relies on the pass, you have to, you know, have time to pass.
