GMs put teams together, but how does that equal a win or loss? Here are some factors out of a GM's control, some that I've stated earlier: -Individual motivation and performance, including career years -Luck, including timely hitting and pitching (I don't really believe in "clutch") -Fluke and unforeseeable injuries -Managerial decisions, which is quite different from hiring a manager -Coaching effectiveness and strategy, again, different from hiring them -How good and competitive opponents are Things like that also have big impacts in whether games are won or lost. That's not too far off from the things a pitcher can't control. Basically, GM moves do not equal wins or losses. They play an important part in the season's results, but by no means is it up to them to win games. And because of that, wins and losses, which are a collection of efforts from the GM, the manager, the coaches, the players, the minor leagues, luck, etc., should not be used to tell whether or not a GM is doing a good job.
