And I wouldn't blame either one for leaving early. They'll both get drafted.
Kalani's job isn't to recruit them to stay. His job is to give them honest advice and feedback based on what they've received from NFL scouts. If Kalani is getting info back saying "so and so could use another season to show us more" then he'll be very upfront and relay that information along with his own advice. And just the opposite....if a player is getting a draftable grade, especially an early to mid round grade then he'll likely tell the kid..."We'd love to have you in our program, but I support you in whatever you make."
That's what a good Head Coach does...and he does that already.
