I think you should get what you pay for. If you pay for scouting your scouting should be accurate. Most of the arguments I read for randomness only apply to minor league development, IFA or DITR. I hear very few arguments asking for randomness in FA i.e. players signing big contracts and underperforming such as Pujols and Hamilton. That tells me that the discussion really isn't about randomness.
Having said that, I agree with the sentiment of the last 2 posts. I would like to see a system where the DITR is based on a probability factor. For instance there would be 4 players from the top 200 overall rated players that would be coded to be future DITR. The more you spend on scouting the more of the top 200 players you would see, the more draft picks you have the greater your odds to get one of these players. Nobody, however, would ever know who these players are and they would have normal progressions until they have completed 6 seasons, at which time the DITR would kick in and their minimum rating for the effected categories would be a 70. Categories for pitchers would be control, L,R and pitch command. Hitters would progress in either hitting or defense. Health would also be a minimum of 70.
1 a pitcher with 20 control and 75 R, 57 L splits and 38 health would become a pitcher with 70 control, 75 R, 70 L with min 70 command of each pitch with 70 health.
2. A hitter with 96 Power 28 R, 31 L hitter would become 96 Power, 70 R, 70 L hitter with min contact and eye of 70.
What I think this would accomplish is to add a little pizzazz to trading and the draft. Those AAAA players that get traded could potentially be star players and teams drafting lower i.e. 32 in the draft would still have a chance to acquire a top prospect if they spend money on scouting without penalizing the teams drafting higher who spend money on scouting... in fact the best player in the draft could be drafted in as low as the 5th or 6th round.
