Suggestion
In making the batting lineup the AI needs to take a better overall look at speed, power, bat skills to more sensibly place players. The AI needs to take a more global look at defensive positions, and shift players to maximize team defense whenever a new lineup is made or substitutions are made. And the AI needs to take a more global look whenever it makes a PH/
PR/reliever move.
Reason
Playing out games it is frustrating to see the wierd lineups and lineup moves the AI managers make. Although human managers will vary in how they place players, its hard to imagine any coming up with the lineups often made by the AI. AI substituting needs a lot of work. The AI roster usage is very inefficient in often using too many players. It too often pinch hits for the wrong players, with the wrong players, and too often uses a third player in the field, who sometimes would have been the better pinch hitter.
Priority
High. OOTP has established a great platform. Now its time to go back and refine the details that will make it so much better.
