Step 1: Blow all three timeouts halfway through the third quarter

Step 2: Run a QB sneak on fourth and two (even though Marcus Stroud has been lining up over Nalen all day) instead of taking the three points.

Step 3: Go for it on fourth down backed up against your own endzone with four and a half minutes left.

Step 4: ??????????

Step 5: PROFIT

Even if you want to claim Shanahan was forced to go for it on that fourth down, he was only forced to go for it because he's an idiot and wasted all his timeouts and didn't kick the field goal earlier.
