Yeah, I agree where the issue with adding the N/A spots right now wouldn't have to do with increasing the roster size. I don't like looking at the free agent wire in a league such as this and seeing someone that's 40% owned - wanna get that into the single digits
I believe the strategy in a dynasty league such as this is to be able to foster enough talent on your own roster for whatever situations may occur. I don't like how often in the past I've had to drop a player I actually considered to be good, I like to leave those types of decisions to the shallower re-draft leagues I play in.
I believe as thatcoolguy mentioned, it may come down to an issue involving previous strategy already this season assuming we would just have our 30 man rosters. I've already dropped 3 players this year that would have been eligible for my NA slots. Maybe we'll be able to come up with something though. If we did add the slots this year, it could allow thatcoolguy to store even more prospects if he wanted to.
