Babb fell to #164 in Rivals updated rankings. Below is what they said about him.
Analyst’s take: “Babb was having another outstanding summer and his stock continued to elevate, but his senior season was lost with an early camp ACL injury. He lost part of his junior season to a leg injury as well, and will have played just six games over his last two high school seasons. Babb remains uncommitted, with a top nine schools that includes LSU, Nebraska, Ohio State and USC.” - Helmholdt
So they basically admit to dropping Babb only due to his injury.
