No that one was more defensible. There are statistics from that season that show Lynch was far from a guaranteed TD there.
It's 3rd and 1 on the last drive of the Super Bowl and your #1 RB is picking up almost 5 yards a carry. Perine up to that point had 1 carry for 0 yards. And they give him the ball on a simple HB dive? One of the worst decisions I've ever seen, Super Bowl or otherwise.
