What am I doing wrong

Quoth Yogi Berra

Hal doesn't like that succesful teams in regular seasons continue on their lucky strike in the playoffs. That's why Hal tweaks the system so that only one team wins at the end.

Love the Yogi quote. Nice to end the day with a laugh.

no extra stuff for the playoffs, e.g., some playoff clutch something on certain players

To my knowledge there are no such things in place. But then again you never know for sure with strat. And true or not I am sure it would not be difficult to start a grassy knoll theory on this one.

If one wanted to be sure I suppose you could check old strato leagues where Arod was on a playoff team.......
If they were going to do some such thing sure he would be involved.
