No, no, no! The whole point is that you measure the right thing in order to reward people: whether bottom line club profits or in footie terms league position etc. Rewarding the buying and selling of players distorts the process of achieving success for the club. It's the same in business as I pointed out. Anybody who has dealt with metrics in business/computing knows you have to measure the right thing: no good achieving 100 transactions per person per day if 50% are incorrect or you are miss-selling PPI insurance or whatever..
