What is your point? Glendening is still playing just as hard and pretty much the same level as then. Why is Nielsen brought into this? One player aging poorly/dropping off means every player hits the same thing?
It was just to situate how far in time it was. Using an example from 5 years ago to describe a players current ability isn't very convincing to me.
As for Glendening current play, I haven't paid much attention so I can't say.
