The dude isn't going to define himself in 5 minutes. He did define himself against Minnesota, and he was a big part of a 15 point quarter for Indiana.
Reading between the lines, the choice is being made to keep Bargnani
on the floor for around 40 minutes per game, and needing more size than what Ed can deliver in order to compensate for Andrea's deficiencies and unwillingness to use his own size against 5’s. Ed isn't the only one to pay a price, as Valanciunas can't really get afforded the chance to develop within games while needing to worry about covering for Andrea at the same time. There is a reason Aaron Gray was a no-brainier and will continue to get minutes. The question is - is that really the direction we want to go? When the league is getting smaller and playing small ball more often, why are we stuck on playing one big that has to be paired with another big at almost all costs? Any way you look at it, unless we move Andrea to a sixth man role, where he could prove to e far more consistent than he is now, we are limiting this team, and making the coach look like an ass.
