What is the core strategy of the Louisiana State University Tigers' ground defense against Li Wei?
Speed.
Because they knew Li Wei excelled in speed and burst, but his weakness was in confrontations and strength, they adopted a double-linebacker man-marking tactic, with Riley and Beckwith providing double insurance, disrupting Li Wei's acceleration front and back, ultimately outnumbering him and piling up like sandbags to complete the stack.
This was also the conclusion they drew from all the games of the Crimson Tide Storm thus far.
It must be said, they conducted an all-around analysis of Li Wei and came up with targeted tactics, even considering the offensive line and tight end's blocking assignments and so on, going all in to cut off this point.
