There was an article a while back about the concept of Big Game Syndrome (no longer available). It focuses on football, but the idea applies to any sport.
The article described Big Game Syndrome as a situation where a team or coaching staff feels they must do even more work and be even more uptight than usual when facing a perceived important game or match. The prime example provided was football teams facing the New England Patriots. The view is that they need to do something extra special to outsmart Bill Belichick. The result is decision-making which goes down poor paths.
While coaching in Sweden once, I found myself wondering if I’d succumb to a version of Big Game Syndrome with respect to my team’s matches. We spent the better part of a week talking about that match. In particular, we focused on the other team’s big attacker. The result was that we were probably too focused on the other team and not focused enough on us.
Of course there are times when looking for any possible edge you can find to win is important. To my mind, though, I felt afterwards like I made the mistake of doing that sort of thing at a time when our focus should have been the development of our game.
On the face of it, the fact we went up 2-0 suggests I was wrong. Maybe we spent the right amount of time on scouting and game planning. The fact of the matter is, though, we won those sets despite not playing very well. This was especially in the first set. We didn’t get a kill until our 10th attack. The other team kept us in it by missing a bunch of serves.
The over-thinking element came into play later in the match. We felt the pressure of trying to fend the other team off when we had late leads. It made us hesitant and cautious and led to some poor decisions.
