It's common to hear Coach Shanahan called a genius. Sunday's Green Bay game is a test of that high praise. He has had 145 days to prepare for this battle. The RB are banged up. Nobody expected this deep unit to be so devastated two games into the season, but here we are. Mitchel is a gold nugget drafted in the 6th round. He's played well against stacked lines. Teams understand that Shanahan features the running game, which includes many short passes that rely on yards after the catch. So they put up 8-man fronts that makes runs up the gut futile. The O-line's feature is mobility, not road grading.
So what does a genius do with a decimated running corps? He improvises. He adds some plays that can be called the "Wilson bundle." The last game of the SB 2019 regular season found the Niners shutting down Seattle in the first half. Zero. Then, as routine, as the D gets tired Wilson begins his magic. He extends plays for four seconds or more, allowing receivers to get deep for his deadly long throws. In the end the Niners win by six inches, when most think the game should have been won by ten points, by the better team.
Who enters the game in the Wilson bundle? A guy named Trey Lance. What about Garappolo? He's still the QB. Lance enters as a receiver, TE or back. One obvious play is the Deebo Special. The end-around. Only now it's Deebo2, Lance. You now have an extended play with dynamite options. Two can be running deep patterns while KIttle is dragging two guys covering him. Some is going to be open after four or more seconds. Announcers are always saying, "cornerbacks can't be expected to cover a broken play."
Only a Wilson Play isn't a broken play. It's just a play to break the foe's tendency to crowd the line of scrimmage.
