Shutting down Mali is easy and they will probably will. He is not a big guy like jeremiah Smith.
Dawson for whatever reason doesn’t allow Mali to play multiple positions like Ohio State does with Smith. It makes it harder to scheme. They will do what Clemson did.
It is very hard to bracket or double out the slot because it leaves a lot of single coverage on the outside. While Mali may not have a great game statistically, he will contribute to many plays because of his gravity which will leave his teammates open.
