My guess is they told him to get it and he said "well it might make me redshirt, you gonna guarantee me a slot?" No guarantee, no surgery.
He took his chances that someone would bite, and now he's being punished for not being a Team Guy. The next guy who gets told to get a surgery will get it.
I would for sure draft that guy. Same as Honey Badger, same as La'el Collins. This is NOT why you don't draft a guy.
