Let me amend my previous answer. "Very conservative" means you will draft guys who are "openly signable". That includes slot money guys, but also includes "Looking to be drafted in the first round" if they're your first round pick and "Looking to be drafted in the first five rounds" if they're a first five round pick.
Slot money guys sign right away when you meet their demands. The other two examples may or may not come back and ask for more.
What is the signability for your guy, and where did you draft him (what round)?
