In Jeff's quasi-defense, he devoted his life to playing baseball, which has a defined set of rules. You either follow them, or you don't. I think his issue with Survivor and the other contestants is, they didn't have the same style of game play as he did. He charged in with a plan, determined to win. Sometimes this works, but it didn't for him for a number of reasons. We've seen players with a variety of strategies make it to the end--as viewers, we may prefer to see certain strategies work, but sometimes you get the coat-tail people there, sometimes the "never won a challenge" people, sometimes the "give it 1000%" people.
In Jeff's case, he lost his focus on the end game, and focused too much on getting rid of Penner specifically.
P.S. When Malcolm said he taught in Micronesia for a year, my DD17 declared him "perfect!" She wants to teach abroad, and wouldn't mind some eye-candy when she does it...
