At what point is execution a coaching problem?

Does it not look like Juwan Johnson was reluctant to block? How do we solely blame coaching for a player’s hesitation?

You can blame coaching for not making sure Juwan knows what he’s doing. But Juwan has as much blame for knowing it’s a screen play and that he’s a blocker, but not blocking the immediate defender near the go to read receiver. Our players aren’t as good as we think they are, even in basic fundamentals.

Moreau would’ve been the better TE to have in for blocking on a screen. But coaches used Juwan as a decoy.
I thought Johnson was just out there kickin' it. Thinkin about what slimmy was gonna pass by the crib later on, you know, the important stuff in life.
