Another thing that seems logical, but do we have any imperical evidence?
Are there any studies showing that players are worse if they play more games?
There's a lot of traditional old school theories on how much playoff experience plays into a team's chances, how going into the playoffs 'hot' or 'cold 'plays into a team's chances, how a players' playoff history plays into how well he will do, and so on. And since we've been told that all our lives, it's got to be true.
All of it scientifically proven ;-)
