Yes but...….Accepting a poorer scoring rookie just because they are dirt cheap isn't always the best strategy, just as our ''Premo'' selections are versing every other coaches premo selections in the same spots, so too are our rookies. Even if it's a non playing bench spot, our rookies are all competing against other coaches rookies to increase cash, by round 8 some people who took a Gibbons at 102k or a Parker at 117k because they wanted to squeeze that extra 15k (102 rookie) or 6k (117), may end up regretting watching a guy averaging 40 on their bench making stuff all while someone else has already made 80k more from a guy going at 65 or w/e.
This is all theoretical granted, and i agree that a Gibbons or Parker may well indeed have some spike games and turn out to be better than a higher priced rookie but you'd hate to lose cash generation, have dead wood all for the sake of 15-21k (in some circumstances).
