I have been thinking long and hard about this. Why is there a penalty for add/drops salary-wise? Can anyone give me a solid answer? I would think it would be fun to retool the team midseason, which is really not a practical option once the season starts. It might also get some of those rarely used cards some use.
Also, I would be curious to see which cards get used and how often. Since some of the cards are truly useless, why not cull the herd?
