What is the difference between the meaning of the following sentences:

1: Shaun Pollock has never been so expensive as he is today.

2: Shaun Pollock was never so expensive as he is today.

I would use 1, it shows a continuance in the state of being expensive from the past to the present.

2 implies that that there might have been a period of interruption in his being expensive.
