Athletes who can compete at a high level in their late thirties and into their forties is much more common now than it used to be. I watched the Storm last night and mostly just watched Sue to see if I could see if her game is on the decline. She looked just fine. It's mostly the legs that fail older athletes - the quick first step fades, getting up for rebounds and reacting to get loose balls is a beat slower. Sue's strengths were never being quick and explosive. Her strong suit was/is great court awareness, controlling the game flow, taking and knocking down the shots that are there and passing to teammates at the right time and place. She can still do that and if she had decided to keep playing who doubts that she wouldn't have been able to earn a starting spot on any team in the league? Not me.
I'm happy that Sue is leaving the game as a player on her own terms. Having watched her play from her frosh year at UConn and as a pro have been a treat and privilege.
