Maybe; or maybe not. If Wallace is lined up correctly, the only inside help is Milano who appears to be dropping into zone. Milano initially steps toward Hill and away from Wallace. That opens up the middle for Kelce.
Without knowing what defense was called you can't say who screwed up. Wallace? Milano? Frazier? McDermot?
This is why if daboll gets hired away it's important to keep the same offensive philosophy, play-naming, etc.
