That is what I have heard as well. Search for single season Transfers also. Just as good as a walk-on, normally better.
The other suggestion is, sign crap role players with minute or start promises, then they will leave. Yes you take a rep hit, however starting out at a New School you are normally as low as you can get already. Just two suggestions I have used.
On the other hand, I have filled 9 open Scholarships at D2, all in RS2. Search Juco, Transfers, and actually look at a couple high number D3 States in your search. Most Human D3 Coaches don't even search D3 anymore in RS1, and will wait to see what they luck into from D2. There are ways of team building even in RS2.
