I don't know what "taking" a silent commit even means... There's no paperwork. He's not signing anything. ****, he's not even making a public statement. Nobody outside a small group of people in the program and in his life even knows (at least in theory) that he's "silently committed."
If you mean to say we should tell a kid who wants to silently commit to go kick rocks, then, my friend, that's just dumb. By example, would you have told Al Blades "no," when he wanted to wait to announce on Fathers' Day? That's not going to help with recruiting.
But, if you are saying the staff should be savages on the trail and keep recruiting hard at positions where recruits are allegedly "silently" committed, then I agree 100%. Whether a commit is public, private, or silent, the staff needs to keep recruiting at his position. Until the signed LOI comes in, keep recruiting at his position, especially if it's a position of need.
Every so often, you have a rare kid publicly committed that is out being a brand ambassador for the program and trying to pull in other players in a class like a Duke/Dallas/Lingard/Jordan. Maybe we count those guys as committed before the ink is dry... MAYBE. But other than that, if a recruit is looking at other schools, then we should continue recruiting his potential replacement.
