Looks like an interesting longer article by Richard Moorhead for those with a subscription to Legal Ethics...why 'zeal' may not be the selfless characteristic in a lawyer that some believe it to be.
those lawyers that are more zealous in their outlook, i.e. more inclined to advocate a risky or aggressive strategy, are more motivated by self-interest than are less zealous lawyers. Those with stronger risk-appetites appear less motivated by benevolence for the client. If zeal is self-interested, the risk that lawyers miscalculate the client’s interests is magnified.
