Given the way the current draft works - draftees have all been contacted and more-or-less agreed on a bonus (at least the ballpark, in principle) before their names are announced - one wouldn't expect very many failures to sign early-round picks. There hasn't been an early-round pick that did not sign since 2018 (there were four that summer). Given the constraints that the slot system imposes, there's no rational reason for a prospect or his advisor to indicate they'll sign for a certain range, and then try to negotiate something significantly different. The money simply isn't there - and if a top three round pick doesn't sign, the club gets a comp pick the following year. So a kid has little or nothing to gain by misleading an interested club about what he'll sign for - and a professional advisor can only lose, if it becomes known that he misleads clubs.
