Rensch should not have been commentating today.

We have great talent like Peter Leko, David Howell and Judit Polgar that would have done a fantastic job discussing the final games with Magnus.

Unfortunately Daniel doesn't have the GM expertise or energy today to discuss and challenge Magnus ideas.

Being a Chief chess officer is an important job. However, we have GM talent that are experts at commentating. Use them. Play to your strengths.
