IPL - How do you account the big hitting and tall scores?

It is too early to see a pattern, but two of the most explosive innings in the IPL, have come from teams playing first. Similarly, the centuries scored so far have been by batsmen playing in the first innings. To take it further, there have been more sixes hit by the team batting first than the team batting second.

Probably the frenetic nature of the format is the reason behind the big hitting. Batsmen have to perforce maximise their shots and have found that hitting it over the infield gives them maximum returns.

However, this does not explain why the chasing team finds it difficult to repeat the power hitting.

The most probable and obvious answer is it could be due to over thinking.

Focusing on the score or the fact that one should win the game often trumps a player’s intuitive response patterns (so-called muscle memory) that allows them to just play their game.

If this is the probable reason, then the utility of the coach is questionable. What is he doing if he cannot prepare his wards?
