i'd say that there are two qualities i'd be most interested in - a strong understanding of player valuation, and a consistent vision of what it takes to succeed in the long run. i definitely want someone who will improve the farm system and dedicate considerable resources to international free agency and the draft - that goes more into the second point i raised. i think hendry is pretty poor when it comes to player valuation - he doesn't give me any impression that he understands or uses advanced metrics with respect to defense, he consistently overpays for relievers with mediocre peripherals but good ERAs, etc. it also drives me crazy that every offseason his plan seems to change based on a random weakness of the previous year's team - get more lefthanded, get more speed, etc. it's like playing whack a mole - you steal more bases the next year, but your team doesn't get on base... or you can hit RHP a little better but the team defense takes a hit. have a vision of what it takes to build a good ballclub and stick to it.
