And, I have to say, he is making progress. I'm sure I saw him running in the right direction at least once today.
However, I fear his steady advancement is at risk of being halted after a new coach joined the fold today. Me.
There I was, minding my own business at pitchside with all the other rugby mums and dads, when the head coach - whose name forever escapes me - called on me to assist with the "cat and mouse" game.
This should not have been a huge challenge for yours truly, as it is a drill (albeit with a different name) I took part in hundreds of times myself in my own playing days. But could I remember how it worked? Of course I couldn't. Plus, having an audience of four and five year-olds and their parents watching made me very self-conscious.
The result was that I made something of mouth of myself and the head coach spent more time guiding me than any of the actual players.
I fear I'll not be volunteered again next week, if only to save Jamie deeper embarrassment.
