Come on, just be honest. This isn't about one "simple question", it is about the fact that you bring up walk-ons in every single thread that lists/analyzes the roster.
Nobody cares about "your" roster numbers. The only important measure involves recruits who sign LOIs. Walk-ons don't mean anything, but you are literally the only poster on the board who continually asks questions about the (non) impact of walk-ons.
In the last 40 years, there has never once been a situation at UM where a coach has to tell a recruit "well, we'd really like to offer you a scholarship to UM, but we gave out too many scholarships to walk-ons".
