I do believe that seble has said there is no programming to make a recruit be more willing to accept a RS regardless of how many games he has not played in. There is also no programing making him less likely to accept if he starts both exhibition games.
As far as gaining points, my experience is that guys who are not RS will gain more points than guys who are RS ... though I am not 100% sure that all of the advantage is not just related to playing time. So, riding the bench with 0 minutes might be just like a RS in this regard.
It still makes sense to wait though WRT a WE drop. If you remove and reapply the RS, you can likely get the WE drop down (or to zero), so it is not critical in my estimation ... but if you can't get the WE drop to zero it might be significant.
In GD, you can not RS a guy after week 7 starts ... is there any such limit in HD?
