Well in that case it seems most likely that you did not set your draft order properly. If you have information on a player that has 5 skill balls and another with 2 skill balls, why would you draft a 2 skill ball player over him?? The difference between the two players is that 5 skill ball player have more skills at respectable. Also, by scouting a guy twice you know just how good the 5 ball player is be it a A+,A or A- and also giving you information on his potential, again giving you more information on the player for you to make a decision. I don't see how this information is "somewhat useless" as it is the difference between drafting a player of over a million in value and a guy not even transferable on the market....
Again you refer to DMI. It is called the Deliberately Meaningless Index for a reason. You can't compare players with it. It is misleading to try gauge how good/bad a player is by looking at DMI as a player in really crap game shape will have bad DMI but his skills might be better than everyone on the team.
