couple things:
1) "There is really no benefit to telling a player ahead of time that you plan on redshirting him. From what I've learned from others here, only bad things can come from that" - this is incorrect. by informing of redshirt, you get 100% chance of the player accepting the redshirt
2) "but some coaches say if you inform of RS the same cycle as a bunch of HV, and/or a CV, it goes smoothly with the recruit accepting it" - this is not incorrect, but does not represent a complete understanding, either. doing the redshirt in the same cycle or not, has nothing to do with it. the point is, the inform redshirt is a substantial negative. as correctly stated by stillwaters - "The better the player and the lesser your team, the greater the possibility he won't like the RS... The lesser the player and the better your team, the more likely he is to be okay with the RS".
in short, comparing the player to the team gives the amount of negative value the inform of redshirt will generate. note that goodness of the player is actually, 'goodness of the player as ranked by the incredibly ****** player position ratings'. and 'the lesser your team' just means prestige and division. pulling a scholarship works the exact same way, and this same factor is a major factor in how much effort is required to unlock, and so forth.
anyway, as long as you have enough extra positive effort on a player, you will be able to withstand the negative value of the inform. there is nothing special about doing it in the same cycle, except, that you CAN do it in the same cycle, because the inform of redshirt (or withdrawal of scholarship offer) is processed last, after all the effort (otherwise you would need a cycle of buffer). it does make sense to do these extra hvs and stuff in the same cycle as the inform, because you generally don't go throwing 5 extra HVs on players just for the heck of it, and then have that effort lying around for you to use against the inform.
make sense?
