Oddly designed play. The pursuit basically led the DLine running right towards Josh. If you're going to try something like that, have Cook in the backfield for a reverse to Samuel, then flea flicker. That way the pursuit actually has to change directions and there's more eye candy. Way higher chance of success.
Also side note. If they're trying to find ways to get Samuel in the game plan, why not get him going on some jet sweeps/more quick screens. Seems like those would be things he excels at.
